Christina Aguilera: I Was Forced to Be "Toothpick Thin" in 2002

Christina Aguilera is taking control of her music and of her body.

Appearing on the September 29 cover of Billboard magazine, the 31-year-old singer opens up about the struggle to stay thin in the music industry. "During the promotion of my album Stripped [in 2002], I got tired of being a skinny, white girl," Aguilera says. "I am Ecuadorian but people felt so safe passing me off as a skinny, blue-eyed white girl."

"The next time my label saw me, I was heavier, darker and full of piercings!" the five-time Grammy Award winner laughs. "Let me tell you, that wasn't an easy pill for them to swallow. I had gained about 15 pounds during promotion and during my Stripped tour [with Justin Timberlake, 31]. They called this serious emergency meeting about how there was a lot of backlash about my weight. Basically, they told me I would effect a lot of people if I gained weight -- the production, musical directors."

"[They claimed] people I toured with would also miss out if I gained weight because I would sell no records or tickets for my shows," she adds. "I was young, so I lost the weight quickly and was toothpick thin during Back to Basics promos and touring."

The "Your Body" singer, dating production assistant Matthew Rutler, had finally had enough in 2012. "I told them during this Lotus recording, 'You are working with a fat girl. Know it now and get over it.' They need a reminder sometimes that I don't belong to them. It's my body," Aguilera tells the magazine. "My body can't put anyone in jeopardy of not making money anymore—my body is just not on the table that way anymore."

After the critical and commercial failure of her 2010 album Bionic, Aguilera hopes Lotus (in stores November 13) will remind music lovers of her true talent. "This album represents a celebration of the new me, and to me the lotus has always represented this unbreakable flower that withstands any harsh weather conditions in its surroundings, that withstands time and remains beautiful and strong throughout the years."

"Once I could start writing my own songs, beginning with Stripped, I tried to infuse as much as I could to promote strength and inspire people with that message," Aguilera explains. "And now I'm at a place at 31, where the last time I felt this way was when I was 21 with Stripped and I had a lot to say and a lot to express."

Jennifer Garner Reveals Toned Arms in Strapless Red Dress at Butter Premiere

Red hot mother of three!

Jennifer Garner looked super sexy at Thursday's NYC premiere of Butter in a red strapless Gucci dress.

The 40-year-old wife of Ben Affleck -- and mom to daughters Violet, 6, Seraphina, 3, and son Samuel, 7 months -- flaunted her slim, toned bod at AMC Lincoln Square Theater.

Garner plays a very type-A mom in the new film, but the actress insists she's nothing like that in real life. 

"I am not like her in any way, shape or form!" she told reporters.

"It was just fun. What was so great about playing this role was getting not to be myself," she added. "I'm sick of myself! I went totally the other way and I had a blast.

Joining costars Olivia Wilde, Alicia Silverstone, the busy mom hit the after-party for Butter hosted by Appleton Estate Reserve and Cinema Society at The Double Seven.

During a recent interview with Ellen DeGeneres, Garner said she's happy with having three children -- but husband Affleck, 40, would like more!

"I am not pregnant right now," Garner said on The Ellen DeGeneres Show. "I plan to be done. But my husband is kind of a wonder sperm kind of guy."

"You never don't know," she added. "You just have a look at him!"

Colton Haynes: "I Just Lost 16 Pounds of Muscle"

Staying in shaping isn't easy -- just ask Teen Wolf actor Colton Haynes!

At the Cybergeddon premiere in West Hollywood September 24, the former male model, 24, admitted he's not as burly as he was while filming the MTV series' second season just a few months ago. "I just lost 16 pounds of muscle, but I'll get it back -- it's easy!" Haynes told Us Weekly. "It's so hard to keep it on."

Haynes explained he works with "amazing trainers" to sculpt his bulging biceps and perfect pecs. "I haven't had [a session] in a while, which is why I dropped a little weight, but I'm a huge fan of yoga and spin class," the actor said. "Spin class is the best for your core!"

Of course, exercise isn't enough to keep Haynes' body in mint condition. "Unfortunately, diet is 75 or 80 percent of trying to get in shape, so you do have to try to cut the carbs," he told Us. "The diet's a huge part! I'm from Kansas, so I love ranch dressing and McDonald's. When I'm working, I have to stay away from all that!"

Luckily, eating healthy hasn't interfered with the single actor's love life. "The good thing is when you're going on dates, you want to go to a nice place, so they're [probably] serving chicken and steaks," he explained. "You can eat them with vegetables, so you're good."

Though Haynes was recently (and falsely) linked to Pretty Little Liars actress Lucy Hale, 23, the the hunky star admitted Chris Zylka's ex "is such a special girl in my life." As for what he desires in a significant other, Haynes revealed he's looking for "someone who just wants to have fun and isn't afraid to go out in jeans and a hoodie and just hang out."

Kim Kardashian Reveals Tiny Waist in Gold Belted Swimsuit

Perhaps this will get Kanye West's attention!

On September 24, Kim Kardashian shared a sexy self-snapped picture of herself via Twitter. Revealing her tiny waist, the voluptuous E! reality star, 31, rocked a white Michael Kors swimsuit with a gold belt.

The buxom brunette has never been shy about showing off her curves, telling the September issue of Prestige Hong Kong, "You have to really know your body. Everyone has a body part that they don't like and want to conceal, and something that they like and want to show off. So it's all about knowing what you want to show."

"If you have long legs, you might want to wear short skirts and show your legs off. If you have a small waist, you can always wear belts and do what you can to accentuate your waist," she added. "Or if you want, you can cover up your arms. For me, when I feel good in something, I feel confident."

After a "long day" at the beach in Miami September 24, Kardashian struggled to get some shuteye. "Can't sleep again tonight!" she tweeted. "Maybe it's because my baby Kanye isn't here to cuddle."

Luckily, West, 35, is there in spirit; The "Gold Digger" rapper recently bought his girlfriend a Teacup Persian kitten named Mercy.

Slim, Sexy Jessica Simpson Eats Steak, Chocolate Dessert at Pal's Birthday Party

Treat yoself, J-Simps!

New mom Jessica Simpson has been working hard on her postbaby slimdown -- and clearly, those efforts are paying off.

The Fashion Star mentor, 32, looked radiant on her way in to a pal's birthday dinner Saturday night, showing off lean, toned legs in a super short, sparkly Boyod dress. (By her side for her night out? Fiance Eric Johnson.)

At the celebration -- which took place at L.A.'s Fig & Olive restaurant -- Simpson took a night off from her diet and indulged in Fig & Olive salad, filet mignon, and the Chocolate Pot de Creme for dessert. (She also sipped on a Bellini and took part in a champagne toast honoring the birthday girl.)

According to an eyewitness, new parents Simpson and Johnson, who welcomed daughter Maxwell May 1, were set on making the most of their night out together.

Even though there were more than 20 guests at the get-together, "They were whispering into each other's ears and smiling and laughing a lot," the witness tells Us Weekly. "They spent the majority of the evening engaged in each other's company."

Lady Gaga Poses in Underwear, Says She's Battled "Bulimia and Anorexia Since I Was 15"

Lady Gaga is starting her own "body revolution."

On September 25, the "Born This Way" singer, 26, shared a somber photo of herself wearing yellow lingerie via her Little Monsters website. "[I've battled] bulimia and anorexia since I was 15," Gaga wrote in the caption.

The revelation comes on the heels of the singer's recent radio interview with Elvis Duran, in which she admitted to being on a diet "because I gained, liked, 25 pounds" during her five weeks off between tour dates.

At the time, the Grammy Award winner insisted she didn't "feel bad about" putting on a few extra pounds. "Not even for a second."

"I have to be on such a strict diet constantly," Gaga explained. "It's hard because it's a quite vigorous show, so I tend to bulk up, get muscular, and I really don't like that. So I'm trying to find a new balance."

Proving she's more than just a number on a scale, Gaga shared some words of wisdom from Marilyn Monroe via Twitter September 22: "To all the girls who think you're ugly because you're not a size 0, you're the beautiful ones. It's society who's ugly," the singer quoted the late blonde bombshell as saying. Gaga then added, "Thank you to my fans who love me no matter what  and know the meaning of real beauty and compassion. I really love you."

Months earlier, legendary musician Elton John, 65, said he was concerned about his pop star pal's tiny frame. "She is frail, and she doesn't eat when she should," John said of Gaga. "I know how tiny she is and I do worry about her, yes."

Bristol Palin's Amazing Weight Loss: How She Did It!

Bristol Palin's back on Dancing With the Stars: All-Stars -- with a hot new bod!

Returning to the ballroom alongside her season 11 pro partner Mark Ballas, Palin wowed DWTS judges Carrie Ann Inaba, Len Goodman and Bruno Tonioli with her cha cha, but also impressed with her slimmer waistline.

"I'm definitely in better shape than I was last time, definitely. I'm just more active and I cut all the crap out of my diet! It's that simple," Palin, 21, told Us Weekly backstage Monday after earning a score of 19 points out of 30 from the judges, including Inaba, who declared Palin the "most improved" returning contestant. "And my kid's a lot more rowdy, a lot more active. I'm running after him a lot! He's huge! He thinks he's a teenager already."

Palin's mom, former Alaska governor Sarah Palin and father, Todd, joined her son Tripp, 3, in the audience to watch the DWTS premiere, and the returning celeb dancer told Us her family remains a huge motivating factor in her ballroom success. "If I ever hear anything bad that's being said about me or my family, it just gives me motivation to do better, and that's what I do!" reasoned the reality TV veteran, who starred in Lifetime's Life's a Tripp after her first DWTS stint in 2010.

As they face off against DWTS: All-Stars competition Kirstie Alley, Pamela Anderson and others this season, Palin and Ballas look forward to using her newfound confidence to their advantage in the rehearsal studio.

"We picked up where we left off. We stayed in touch since last time and we just went back into it. We balance each other," Ballas, 26, explained. "I'm loud and obnoxious and she's quiet and chill."

Added his partner: "Mark says he's like a chimpanzee and I'm like a turtle, poking out of my shell!"

Sexy Jessica Simpson Shows Off Lean, Toned Legs on Date With Eric Johnson

Mom and dad's night out on the town!

New parents Jessica Simpson and fiance Eric Johnson enjoyed a romantic dinner along at Fig & Olive in Los Angeles Saturday night. Simpson, who gave birth to daughter Maxwell on May 1, has been working with Weight Watchers to lose the baby weight -- and her willpower is definitely paying off.

Looking especially radiant, the 32-year-old Fashion Star mentor wore a super short sparkly dress for the evening, which showed off her long, toned legs. Johnson, 33, dressed more casually in cargo pants and plaid dress shirt.

Simpson has had the support of her fiance while she works to lose the baby weight.

"The fact that he loves me the way I am right now -- we're set," she told USA Today on Sept. 4. The couple have been dating since the spring of 2010. "He knows I want to feel better in my skin."

"I'm not a supermodel. My body is not bouncing back like a supermodel. I'm just your everyday woman who is trying to feel good and be healthy for her daughter, her fiance and herself," Simpson explained. "I feel like everybody can do what I am doing."

Lady Gaga Shows Off 25-Pound Weight Gain in Tight Outfit

Lady Gaga turned up in Paris on Friday -- and she's likely going to avoid those chocolate croissants!

The "Marry the Night" singer, 26, accentuated her new curves in a tight, leopard-print outfit, black tights and towering platform boots, with her newly auburn hair in a perfectly Parisian, retro updo.

The flamboyant pop superstar (real name: Stefanie Germanotta) has been causing considerable comment for her new, fuller-figured look, and recently fessed up to radio host Elvis Duran that she's indeed packed on some lbs.

"I'm dieting right now, because I gained, like, 25 pounds," the Grammy winner revealed. "And you know I really don't feel bad about it, not even for a second. I have to be on such a strict diet constantly. It's hard because it's a quite vigorous show, so I tend to bulk up, get muscular, and I really don't like that. So I'm trying to find a new balance."

She blames her dad, Joe Germanotta -- who has an NYC Italian restaurant that serves up her fave dishes -- for the unexpected transformation.

"I love eating pasta and pizza," says Gaga. "I'm a New York Italian girl. That's why I have been staying out of New York. My father opened a restaurant. It's so amazing . . . it's so freaking delicious, but I'm telling you I gain five pounds every time I go in there. So my dad wants me to eat at the restaurant, and I'm, like, I've got to go where I can drink green juice."

PIC: New Mom Jessica Simpson Shows Off Leaner Legs in Denim Shorts

Jessica Simpson is slowly but surely getting her pre-baby body back!

The Weight Watchers spokeswoman, 31, showed clear signs of progress while celebrating her fiance Eric Johnson's 33rd birthday in Santa Monica, California, September 20. Wearing denim shorts and red platform heels, the "I Wanna Love You Forever" singer unveiled her leaner legs at Shutters at the Coast Cafe.

In recent weeks, Simpson has been open about her struggle to shed her post-pregnancy pounds. "I'm not a supermodel. My body is not bouncing back like a supermodel. I'm just your everyday woman who is trying to feel good and be healthy for her daughter [Maxwell, 4 months], her fiance and herself," she told USA Today September 4. "I feel like everybody can do what I am doing."

"Nobody wants to talk about their weight. For me, I have had to come to a place where I am comfortable with myself," the Texas native added. "I'm a mom now, and get to be a role model for this beautiful little girl."

Luckily, Simpson has the support of Johnson, whom she began dating in the spring of 2010. "The fact that he loves me the way I am right now -- we're set. He knows I want to feel better in my skin."

Though Simpson is following Weight Watchers' PointsPlus program, she said she doesn't "believe in completely depriving yourself. . . I'm a woman who wants her chocolate. I allot myself a fun-size bag of M&Ms. I eat one of those, and my craving is satisfied. I don't need the whole bag of M&Ms."

The new mom is also working with personal trainer Harley Pasternak about four to five times a week. "I've lost weight every single week," Simpson told USA Today.

Lady Gaga Is on a Diet: "I Gained 25 Pounds"

Lady Gaga's revealing costumes during her Amsterdam tour this week have gotten some attention -- but not for the clothes themselves.

In a new interview with radio host Elvis Duran, the 26-year-old singer admits she's recently gained some weight.

"I'm dieting right now, because I gained, like, 25 pounds," Gaga told the radio show (via Huffington Post) before she headed on tour. "And you know I really don't feel bad about it, not even for a second. I have to be on such a strict diet constantly. It's hard because it's a quite vigorous show, so I tend to bulk up, get muscular, and I really don't like that. So I'm trying to find a new balance."

Gaga blames her dad Joe Germanotta's restaurant as the reason for her recent weight gain.

"I love eating pasta and pizza," says Gaga. "I'm a New York Italian girl. That's why I have been staying out of New York. My father opened a restaurant. It's so amazing . . . it's so freaking delicious, but I'm telling you I gain five pounds every time I go in there. So my dad wants me to eat at the restaurant, and I'm, like, I've got to go where I can drink green juice."

But some may argue that Gaga doesn't need to go on a diet.

Back in April, the "Born This Way" singer was criticized after she tweeted, "Just killed back to back spin classes. Eating a salad dreaming of a cheeseburger. Pop singers don't eat. I was born this way."

In June, Gaga's good friend Elton John expressed concern over Gaga's thin frame. She is frail, and she doesn't eat when she should, and she's a girl, and it's tougher for a girl," John told The Guardian. "She works really hard. She will be in Denmark one night and Saudi Arabia the next. I know how tiny she is and I do worry about her, yes."

See Will Arnett's Amazing Abs in Up All Night Promo

Even though his nine-year marriage to Amy Poehler is ending, Will Arnett has never looked better!

The actor, 42, showed off his sculpted arms and six-packs abs while shooting an Up All Night promo with his costar and on-screen wife, Christina Applegate, 40, in West Hollywood August 11. "Will looks really good right now. Everybody is talking about cut he is," a source tells Us Weekly. "He's been working out and his skin is really great."

Despite separating in early September, a source close to Arnett and Poehler told Us "they have a lot of respect for each other," and another insider called their split "very amicable." Indeed, Arnett and his sons, Archie, 3, and Abel, 2, were spotted attended Poehler's 41st birthday party over the weekend.

Even still, the couple's separation shocked both friends and fans alike. "The past few months have been rough for them," an insider told Us, "but I don't think anyone in their circle saw this coming."

Poehler is currently promoting the sixth season premiere of Parks and Recreation, though she hasn't yet been asked to address her recent separation. The Saturday Night Live alum is, however, happy to talk about her two boys with Arnett.

"I'm pretty strict with them," she said on the Ellen DeGeneres Show September 20. "I'm big on manners and 'please' and 'thank you.'"

Even still, "They are boys, so they're kind of crazy," Poehler admitted. "Mothers come over with daughters and we have play dates. My house is a little crazy -- everyone's kind of running around, jumping off furniture. They'll bring their daughters over and the daughters will be like, 'Should we sit in the corner and cooperate?' My guys are like, 'I made chocolate soup.' They will just make dirt soup. And the girls are making like a birdhouse out of organic materials.  It's different."

Arnett's Up All Night premieres September 20 at 8:30 p.m. EST on NBC, while Poehler's Parks and Recreation premieres on the same network at 9:30 p.m. EST.

Uma Thurman Debuts Slim Post-Baby Body on Red Carpet

Welcome back, Uma!

Uma Thurman was back in her gala finery in NYC on Wednesday evening, attending her very first red carpet event since welcoming her third child, a baby girl, in mid-July.

The Smash actress and former model, 43, looked serene and impressively slim at the Annual Brazil Foundation Gala Party at the American Museum of Natural History. Thurman wore a deep purple, floor-length silk gown with a plunging neckline.

At the svelte-again star's side was on-again financier love Arpad Busson, the father of Thurman's baby girl, whose name has yet to be revealed to the public. The twosome began dating in 2007, called off an engagement in 2009, and finally reunited in 2011.

Their daughter joins siblings Maya, 13, and Levon, 10, Thurman's kids with ex-husband Ethan Hawke.

"Uma was definitely not planning on having another kid," a source said when Us broke the news of her pregnancy in February. "It was a surprise, but she's over the moon about it. Very excited."

Nicole Kidman Shows Off Hot Body, Cleavage in Sheer, Skimpy Lingerie, Talks Tom Cruise Split

Talk about an award-winning body of work!

Nicole Kidman graces the September issue of V magazine -- and inside its pages, the 45-year-old Paperboy star and mother of four doesn't wear a whole lot.

In stunning, sexy photos taken by famed celeb photographer Mario Testino, the Oscar winner seems to channel the over-the-top nymphomaniac she portrays opposite Zac Efron and John Cusack in Paperboy. In one shot, the super-pale Australian actress reclines in a tiny, see-through red lace bra and panties. With teased, 80s-style platinum blonde hair and dramatic makeup, she shows off her toned legs in another shot, wearing a black-and-pink bra and a neon miniskirt. A third black-and-white closeup image shows Kidman flaunting her cleavage in a form-fitting light-toned bra.

"I would be more outlandish if I could," Kidman tells V magazine. "A lot of times you just don’t get the chance."

Still, in one talked-about scene from Paperboy, Kidman's character gets pretty outlandish -- urinating on Zac Efron after he's stung by a jellyfish.

"The peeing thing, I didn't think was that weird, because I was in character," she explains. "That was for the jellyfish. And for me it said so much about Charlotte. One, she's protecting him. Two, she’s tough as nails and no one else is going to pee on this guy. All of that made total sense to me. I just went for it and didn't overthink it."

Kidman also opens up about signing on to The Hours -- her Oscar-winning role -- hours after divorcing Tom Cruise back in 2001.

"If you're being completely drained in your personal life and you’re never being nourished there, it's very hard to make it work," Kidman admitted, who was inspired by the film's director Stephen Daldry. "But sometimes, if you meet the right person who will mine it, and you're open to being mined, it can really work. Stephen was able to mine me. I was crazy in love with him, and so I was like, I'll do whatever, because I love you. I gave him every part of me that I could give him." Kidman, who shares kids Connor, 17, and Bella, 19, with Cruise, 50, married Keith Urban back in 2006; the couple share daughters Sunday, 4, and Faith, 20 months.  Cruise and third wife Katie Holmes finalized their divorce on Tuesday.

One lesser-known fact about Kidman? As a child, the she wasn't allowed out in the sun between the hours of 10 a.m. and 3 p.m.! "At the time I thought it was the cruelest thing, and now I know it was the greatest gift," she muses. "I probably had a strong sexuality as a child, so that informs all that yearning and wanting things, and the hormones that are running through you at a really early age—they all started to surge because of the things I was reading."

PIC: Laura Dern, 45, Shows Off Hot Bikini Bod at Beach With Daughter

She's "The Master" of the abs!

Laura Dern took advantage of the scorching hot temperatures in Los Angeles on Tuesday to hit the beach -- and show off her stealth bikini bod!

The 45-year-old actress -- who costars in the buzzed-about new film The Master -- hit the surf with Jaya, her 7-year-old daughter with ex Ben Harper. Showing off an enviable set of abs and toned arms, the Oscar nominee wore a striped bikini top and plaid board shorts.

She and singer Harper, 42, also share a son, Ellery, 10; following a brief reconciliation, Dern reactivated dormant divorce papers back in July.

But Dern was part of a much happier romantic story this past summer: Back in July, Dern (with Ellery and Jaya in tow) dined in NYC with Courteney Cox (plus her daughter, Coco) and Justin Theroux. One of Jennifer Aniston's closest pals, Dern broke bread with Theroux shortly before he proposed to his Wanderlust costar, 43.

"Everyone seemed to be having fun," a source adds of the dinner, which took place at Aniston was on location shooting We're the Millers in North Carolina.

Jennie Garth Explains How She Got So Skinny

Lookin' good, Jennie Garth!

Though her recently slimmer frame raised eyebrows earlier this summer, newly-divorced Garth confirms she's losing weight the old-fashioned way: Through a careful diet and lots of exercise.

"I'm just taking care of myself: Eating less, exercising more, drinking a lot of coconut water," Garth, 40, told Us Weekly at Thursday's Old Navy Denim Pop-Up Bar event in L.A.

Garth has admitted that her March split from Nurse Jackie's Peter Facinelli after 11 years of marriage has taken a toll on her body -- but says that she's not necessarily reaching for comfort foods all of the time. "I eat a lot of Greek yogurt: Greek yogurt in the morning, salads and proteins the rest of the day and maybe a cupcake if I've been a good girl," explains Garth, who works out with trainer Shannon Stewart. "I don't believe in depriving yourself of things you want."

The mom of three daughters, Garth has begun to start dating again in the wake of her split. "She's happier than ever!" says a friend of Garth, who romanced HGTV star Antonio Ballatore post-split and has recently been on dates with hunky photographer Noah Abrams.

Thursday's Old Navy party provided Garth with an opportunity to show off her slender, sexy new bod to her old pal Luke Perry, with whom she recently reunited to film an Old Navy commercial. "It was weird, it was like no time had passed and we were back on the set again," Garth tells Us of filming the commercial with her former Beverly Hills, 90210 costar. In fact, their Old Navy reunion is a sign of things to come.

"We want to work together again because we really love each other and it would be nice to spend time together working," says Garth, who is currently writing a sitcom with Perry, 45. Adds the actor, who played 90210's Dylan: "t's a good day at work when you're with people you know and that you like."

Too bootylicious for her own good?

She's got one of the most famous posteriors in the world these days, but Kim Kardashian fretted over the weekend that she looked less-than-flattering in a pair of skintight jeans.

The most recent episode of Keeping Up with the Kardashians, meanwhile, laid bare some considerable tensions between Kim and her siblings -- especially little brother Rob, 25, who burst into tears during a family therapy session.

Another major red carpet moment for Jordin Sparks.

The Season Five American Idol victor, 22, showed off her incredible 50-pound slimdown at the USTA's US Open Opening Night Gala in NYC Monday night in a skintight, crochet white dress and nude heels.

On the red carpet, Sparks -- who wowed gala attendees with her performance of the National Anthem -- opened up to Us Weekly about staying in shape despite the demands of her jam-packed schedule.

Sparks, usually a gym buff, admitted she hasn't had as much time as she'd like to fit in workouts while she travels the country promoting Sparkle. "It's been so crazy . . . that's where really watching what I eat comes into play," she explained.

"I've been trying to stay away from all of the stuff at the airports, because that's where I've been living," the pop star, who debuted her new figure last year, shared. "I've been trying to eat a lot of salads, apples, fruits -- I've been trying to stick with things like that so I can snack on those instead of being like, 'Oh look, a bag of chips! I'll just have those!'"

Though she does her best to nosh on healthy fare, Sparks admitted she lets herself indulge when she finds herself facing a serious craving. Her favorite feast?

"In-N-Out burger, for sure!" she told Us. "Well, that, or my mom's sweet potato casserole. It's a good thing she only makes that once a year because I would eat it all day long!"

Halle Berry, 46, Shows Off Incredible Bikini Bod

Hot mama Halle!

Summer may be officially over, but that didn't stop Halle Berry from flaunting her ageless figure in a bright blue bikini Sunday in Malibu, Calif. Wandering the beach near her Malibu home, the 46-year-old mom to 4-year-old Nahla showed off her taunt tummy and long lean legs in the blue swimsuit top and cutoff jean shorts. Also on Sunday, she covered up -- just a bit -- joining her fiance Olivier Martinez to run errands, wearing a chic sheer coverup.

"Halle's body looks 10 years younger, at least. She's an inspiration!" the actress' trainer Nat Bardonnet has told Us Weekly. "We try to get rid of what she doesn't like while keeping her womanly shape: erasing thighs, keeping the butt high, lengthening the hamstrings, and working the abs."

To stay fueled between workouts, the actress keeps her metabolism in check by eating five small meals a day. On Berry's menu: salads, fish and soups, which double as anti-aging, wrinkle-fighting foods. "I always had to diet," the 5-foot-6 Berry has said. "It's a lifestyle for me."

Berry's hot bod wasn't the only thing on display during her weekend at the beach: The actress also proudly flaunted her huge engagement sparkler from boyfriend of two years Martinez, 46. Confirming their engagement in March, Berry "had given up on being married, but she trusts Olivier," an insider tells Us. "He makes her feel safe. He's a keeper!"

The musicians most recently collaborated on the song "Bit Fat Bass" from Spears' seventh studio album, Femme Fatale. Until their new collaboration released, Spears will be focused on promoting the second season of the X Factor, premiering September 12 on FOX.

"It's the best feeling when someone comes on stage and makes us want to stand up, gives us energy and makes us feel alive," Spears has said of being a judge with Simon Cowell, 52, L.A. Reid, 56, and Demi Lovato, 20.

Emily VanCamp Reveals How She Got Her Hot Revenge Body

Emily VanCamp is in the best shape of her life, thanks to her role as Emily Thorne/Amanda Clarke on the hit ABC series Revenge.

The 26-year-old actress appears on the September cover of Hamptons magazine, where she reveals her favorite method of exercise. "Pilates is probably my favorite way, but I want to get back into yoga," VanCamp says. "When I'm working, I find it's the best way to balance working on your body and also your mind and spirit."

Though her role can be physically demanding at times, VanCamp is well equipped to perform. "Luckily I had ballet training. At the end of the day, a fight scene is choreography; we're developing the character as we go," she explains. "I've definitely been thrown for a few loops -- trying to memorize the Japanese. But that's what I love most about this character. This is a girl who has gone off and trained intensively for eight years. She's incredibly skilled."

VanCamp doesn't anticipate shooting many girl-on-girl fight scenes, but she isn't opposed to it. "I'm all about strong female empowerment," she laughs. "It's funny: a lot of men watch this show, and I don't think any of us were expecting that in the beginning. They're more hooked than their wives! It's kind of hard not to look. It's like watching a train wreck."

Though fans might "love" to see VanCamp throw down with her arch nemesis Victoria Grayson (played by Madeleine Stowe, 54), the actress doesn't think the show's creators will let it happen. "I don't think she's as much of a physical fighter as she is with her words -- that's her tool against people. We have this underlying banter that is masked with smiles and laughs. That's almost more fun."

VanCamp is careful not to reveal any plot spoilers from Revenge's upcoming second season -- and she's just as tight-lipped when asked about her eight-month romance with costar Josh Bowman, 24. "We don't really talk about our relationship," she tells Hamptons. "The show becomes about your personal life if you talk about it too much."

For now, VanCamp has plenty of other things to focus on. "Last year was the hardest I've ever worked," she admits. "I'm trying to sleep as much as possible to gear up for season 2!"

Hayden Panettiere: I Struggled With Body Dysmorphia as a Teen

Growing up in the spotlight hasn't always been easy for Hayden Panettiere.

When she was just 16 years old, a tabloid magazine published a photo of the Heroes star's backside with the word "cellulite" plastered across the image.

"I was mortified," the Nashville actress, now 23, tells the October issue of Women's Health. "It gave me such body dysmorphia for so long. But I remember reminding myself that beauty is an opinion, not a fact. And it has always made me feel better."

Even so, Panettiere's profession has made the 5-foot-1 actress keenly aware of how her body looks on camera. To stay in shape, Panettiere regularly takes the stairs and often attends Bikram yoga classes. And though she loves eating healthy foods like egg whites and strawberries, the Whaleman Foundation spokeswoman doesn't follow a particular diet. "Eating healthy is a constant battle. I love chips," Panettiere tells the magazine. "I find when I'm overly concerned about what I eat, I stress out my body and put on weight."

Perhaps most importantly, Panettiere says she looks her best when she feels her best.

"People can tell when you're happy with being you and when you're not. It's only cheesy because it's true," she tells Women's Health. "As I've gotten older and grown into my body, I've started realizing that the way you carry yourself and that light coming out of your eyes are the most attractive things about you."

Jennie Garth Unveils Thin, Toned Bikini Body in Las Vegas!

If you've got it, flaunt it -- and that's exactly what Jennie Garth did over Labor Day weekend.

The former Beverly Hills, 90210 actress, 40, made a splash when she donned a skimpy neon yellow bikini at Azure Pool at the Palazzo in Las Vegas September 1. The slender mother-of-three, 40, removed her black cover-up and listened to DJ MomJeans before jumping into the deejay booth herself with actors Danny Masterson, 36, and Michael Pena, 36. Garth also lounged poolside with a gaggle of girlfriends and chatted with Pretty Little Liars star Ashley Benson, 22, and Glee hottie Chord Overstreet, 23.

Garth, who split with husband of 11 years Peter Facinelli in March, "is happier than ever," a source recently told Us Weekly. "She looks like the old Jennie!"

Dr. Eric Braverman, author of The Younger (Thinner) You Diet, recently estimated the star lost 20 pounds in the last three months. And a source told Us the slimmed-down star's waist size is now 25!

Garth opened up to Us about her recent slimdown at an Old Navy Denim Pop-Up Bar event in L.A. August 23. "I'm just taking care of myself: Eating less, exercising more, drinking a lot of coconut water," the former What I Like About You star explained.

"I eat a lot of Greek yogurt: Greek yogurt in the morning, salads and proteins the rest of the day and maybe a cupcake if I've been a good girl," added Garth, who works out with trainer Shannon Stewart. "I don't believe in depriving yourself of things you want."

Garth -- who is developing a new sitcom with her Beverly Hills, 90210 love interest, Luke Perry, 45 -- is "feeling good in her skin," according to a pal.

The the newly single mother of daughters Luca, 15, Lola, 9, and Fiona, 5, isn't just feeling confident about her body: she's also feeling lucky in love. (Garth romanced HGTV star Antonio Ballatore post-split and has recently been spotted out with hunky photographer Noah Abrams.) "She's been going on dates," said an insider. "She's not looking to get into anything too serious so fast."

Bikini-Clad Jennifer Lopez Flaunts Tight Abs, Swims With Casper Smart

Muy caliente!

Hours before she performed at the American Airlines Arena in Miami, Florida, September 1, Jennifer Lopez, 43, sneaked in some pool time at a local hotel with her twins, Max and Emme, 4, and her boyfriend of nearly a year, backup dancer Casper Smart, 25.

After taking a dip with her twins, Lopez spent some quality time frolicking in the pool with Smart. At one point, the former American Idol judge wrapped her legs around the choreographer as he waded in the water and soaked up the sun.

Lopez recently turned to celebrity fitness guru Tracy Anderson to keep her in shape while touring with Enrique Iglesias. When the entertainer is pressed for time, "We skip dance cardio, since she's always rehearsing, and do legs and arms," Anderson told Us Weekly earlier this year.

During her trainer's rigorous workouts, Lopez depends on high-energy tunes to keep her motivated. "She's dedicated!" Anderson raved.

Jessica Simpson: I'm "10 Pounds Away From My Pre-Baby Size"

Weigh to go, Jessica Simpson!

Four months after the Fashion Star mentor, 32, welcomed daughter Maxwell (with fiance Eric Johnson, 33), the Texas native is sharing the secrets of her success on Weight Watchers with the new issue of Us Weekly (on stands Friday), featuring stunning outtakes from a recent photo shoot.

"I'm 10 pounds away from my pre-baby size," says Simpson, who got up to 170 pounds while pregnant.

Sharing a typical day in her diet, Simpson says she wakes up at 7 a.m. to feed her little girl, then eats breakfast: half a Flatout flatbread sandwich with egg whites, peppers and fat-free cheddar (6 PointsPlus).

An hour later, Simpson straps on a pedometer and hits the streets with Johnson and Maxwell. "I'm trying to do at least 14,000 steps a day," the singer says. Simpson also exercises four times a week with pro trainer Harley Pasternak. In each 45-minute session, Simpson begins with a cardio warm-up, followed by circuit training that includes dumbbell triceps extensions, hamstring curls and crunches with a medicine ball throw.

"Her waist is going in, and her thighs are getting smaller," Pasternak tells Us of his A-list client.

Simpson -- who says she makes lunch "her biggest meal" to keep her full throughout the day -- will unveil her svelte figure in a series of Weight Watchers ads, debuting September 10.

Now that she's a mom, Simpson tells Us, "I believe I can do anything!"
