Beyonce Flaunts Amazing Bikini Body in Sexy New H&M Campaign: Pictures

She's a "Grown Woman" for sure! Beyonce is the star of H&M's new tropical-island themed swimsuit campaign, and the 32-year-old superstar showed off her world-famous body in multiple bikinis for the jaw-dropping ads. In one, the singer (whose Mrs. Carter World Tour kicks off Monday, April 15 in Serbia) boasts her toned, curvy physique in a yellow, crochet-style two-piece with a tropical flower in her hair, gold bracelets and huge hoop earrings.

She looks every bit the bombshell in a green-and-white tie-dyed bikini for a second image; in the third, skimpiest look, the "Grown Woman" singer reclines on a pool raft in a tiny, black fringe-bikini.

(Lest fans forget, Beyonce gave birth to daughter Blue Ivy Carter 15 months ago, and has previously said she gained 57 pounds during the pregnancy.)

The Grammy winner had a hand in designing the new affordably-priced swimsuits for the global retailer, Ann-Sofie Johansson, H&M's head of design explained. "I've always liked H&M's focus on fun and affordable fashion," Beyonce explained in an April statement. She added of the pieces: "I really loved the concept we collaborated on to explore the different emotions of women represented by the four elements -- fire, water, earth and wind. It was a beautiful shoot on a tropical island. It felt more like making a video than a commercial."

25 percent of proceeds from the collection, called H&M for Water, will be donated to H&M for WaterAid, which helps raise money for the world's poorest people to gain access to safe water.

Keri Russell Bares Her Amazing Abs, Bikini Body for Women's Health

God bless the Americans -- especially Keri Russell! Gracing the May cover of Women's Health magazine, the FX actress reveals a slightly lesser-known side of herself: Her awe-inspiring bod, especially her abs! Next to a blaring cover line that reads "BEST. ABS. EVER," the 37-year-old mother of two and Felicity alum strikes a casually sexy pose in a printed bikini top and extra-short denim cutoffs which emphasize a stunningly taut midsection and lean legs.

Now starring as a KGB agent living under deep, deep cover opposite Matthew Rhys on FX's acclaimed new series The Americans, Russell lives in Brooklyn, NYC with carpenter hubby Shane Deary and their son River, 5, and daughter Willa.

How in the world did Russell maintain that body after babies? "[I have] this really nerdy workout I do in my walk-through closet in our brownstone, " she tells the magazine. "I do a workout video and use my own music --whatever is inspiring to me at that time, like Alabama Shakes, the Cure, or Mumford and Sons."

Her eating habits weren't always perfect, she admits. "I don't think I ate a green vegetable until I was 30," the former Mickey Mouse Club star says. "I didn't grow up with a mom who enforced that at all."

Although she's proud of her shape, Russell confides that a few things have supposedly fallen by the wayside. "I'm not a complainer about age. I think my girlfriends all look so much better now than they did 15 years ago," she begins. "But the thing I notice most is my butt. I used to have a really good, plump butt. Ugh--now my butt's gone. I do wish I had my 25-year-old butt!"

The former child star also credits her adopted home town for encouraging a healthy lifestyle -- sort of! "My number one healthy tip? Everyone should dance more. Everyone should walk more," Russell says, adding, "I mean that's one of the great things about living in Brooklyn and in New York. You get to eat a big rich fatty meal but then you can walk home."

Gloria Steinem Says Criticism of Kim Kardashian's Pregnant Body Is Wrong "Under Any Circumstance"

Sometimes help comes from the most unexpected of places. As Kim Kardashian fights back against critics who call her fat, stars including Gwyneth Paltrow, Helena Christensen, and Jenna Dewan-Tatum have rushed to her defense, saying it's "despicable" to bully a pregnant woman for her weight. And now the reality star can add another name to her list of unlikely allies: Gloria Steinem.

Us Weekly caught up with the famed feminist on April 5 at the 4th Annual Diane Von Furstenberg Awards in New York City, where she voiced her opinion about the recent scrutiny over Kardashian's ever-evolving curves, and about society's attitude toward pregnant women in general. 

"Our bodies are never public property under any circumstance," the 79-year-old activist told Us. "It's wrong, and people in the street who feel the right to touch a pregnant woman's belly ought to be arrested for harassment. Our bodies belong to us, and if we don't invite touching, we shouldn't tolerate it."

Steinem added that the mistreatment of any woman for her appearance, Kardashian included, doesn't just hurt the victim -- it hurts society as a whole. Criticizing people's bodies, she said, devalues both their brains and ours.

"If our bodies are treated as ornaments instead of instruments, that's because we are rebelling because it's an effort to distract us," she explained. "So don't be distracted. Why bother getting caught up in that?"

Easier said than done, of course, especially for Kardashian. The 32-year-old mom-to-be has faced a near-constant barrage of disparaging remarks since announcing in December that she and boyfriend Kanye West are expecting their first child together.

"It's funny because Kourtney warned me that when I get pregnant, people's opinions will be on an all-time high and everyone will chime in!" she wrote on her blog last month. "So I now see what she means."

LeAnn Rimes Shows Off Toned Bikini Body in Tiny White Bikini in Miami Beach: Picture

Spring break, commence! LeAnn Rimes soaked in some serious sun during a recent trip to Miami, Fla. with a female pal, donning a white bikini that showed off her healthy curves on Saturday, April 6.

The country crooner, 30, looked fit in her white-and-gold string bikini as she kneeled on a colorfully-adorned couch while talking on her cell phone at her Miami Beach hotel.

"Miami is way crazier than Vegas!" she tweeted on Sunday, April 7, of her short getaway. A few hours earlier, the singer also posted a photo of herself looking ecstatic as she stood ankle-deep in the waves, clad in a red strapless bikini top, short demon cutoffs and a jean shirt.

"Good morning from Miami," she captioned the carefree shot.

The break is a welcome one for Rimes, who will next launch into a heavy tour schedule that includes stops at Washington, DC, North Carolina and Michigan as part of her promotions for new album Spitfire.

Rimes has previously come under fire for her thin frame, but has been showing off a healthier figure since going to rehab last summer, just ahead of her 30th birthday on Aug. 30. 

"I've been in therapy my whole life," the Grammy winner told the Boston Herald last October. "I like going. I like being able to have that third-party input and someone to listen that has nothing to do with your life. Everyone has an opinion of how I am and how I should be, and now I'm focusing on how I want to be."

"I think it's really hard to deal with Twitter and Facebook and all these social media outlets," Rimes continued. "And it's hard to take it day after day of reading and seeing things that someone you don't even know says about you. As much as you said you don't want it to penetrate, it does, because you're human."

Lisa Rinna, 49, Shows Off Amazing Bikini Body on Family Vacation in Mexico: Pictures

Spring break stunner! Celebrating her 50th birthday this July, Lisa Rinna flaunted her age-defying bikini body while on vacation in Cancun, Mexico with her family on Wednesday, April 3.

The actress hit the beach in a tiny string bikini that showed off her amazing toned bod. Further proving she's still got it, Rinna even played football on the beach.

The Days of Our Lives star traveled to Cancun for a getaway with two daughters, Delilah, 14, and Amelia, 11, and husband Harry Hamlin, 61, to celebrate their 16th wedding anniversary.

The family stayed in a three-bedroom penthouse at Villa del Palmar resort and enjoyed kayaking, swimming with dolphins, snorkeling, and visiting Mayan ruins, a source tells Us Weekly. Dining at Villa del Palmar's restaurants on the property, the source says the family felt like they took a "culinary trip around the world." 

"Loving Mexico," Rinna tweeted April 2. "I don't want to leave!"

Jessica Alba Flaunts Sexy Bikini Body on Vacation With Nicole Richie, Cash Warren in St. Barts

The sun wasn't the only thing burning up the beaches in St. Barts this week! Jessica Alba's smokin' bikini body also generated some serious heat, as she and husband Cash Warren enjoyed a little tropical vacation with friends.

On Thursday, April 4, the 31-year-old Sin City actress -- mom to daughters Honor, 4, and Haven, 19 months -- showed off her flawless, super-fit physique in a sky-blue bikini top with bright-orange bottoms. She appeared to be in great spirits all afternoon and was spotted laughing and playing around in the clear water.

At one point in the day, the sexy star took a break from the surf to catch a few rays on a jetty in the middle of the ocean. Stretching her long, toned legs behind her, she gazed happily out at sea as small waves crashed around her.

The eco-friendly entrepreneur -- she started a healthy-living business called The Honest Company -- also spent some quality time on the beach with her husband, whom she met in 2004 and married in L.A. four years later. They were joined on the retreat by Alba's pal Nicole Richie, a mom of two herself (to daughter Harlow, 4, and son Sparrow, 3). Richie showed off her own incredible bikini body in a bold, teal two-piece.

Alba was clearly enjoying herself on the group getaway, but she's not all play and no work. As she told Lucky in August 2011, just a few weeks before giving birth to daughter Haven, those enviable curves don't come easy. "I have a hard time with portion control, so I have 1,200-calorie meals delivered," she told the mag. "But I also work out, so basically I'm starving. It sucks."

She also recently confessed to Women's Health magazine that she "hates" exercising, especially when it feels like exercising. "I like doing dance classes. That’s fun. Like hip hop class, mixed with like core pilates-type exercises. And sometimes I do sprint intervals just because I hate working out," she said. "Anything where I have to do something but I can get my mind off of doing it, that's so much better for me than anything that's repetitive. Or the music has to be loud and I have to be moving."

Gwyneth Paltrow: I Have the Butt of a "22-Year-Old Stripper"

Well, that's a testimonial if ever there was one! Perennial health nut Gwyneth Paltrow told reporters on Thursday, April 4 that adopting the Tracy Anderson Method has given her a completely different outlook on life -- and a more shapely bum to boot!

Speaking to reporters at the opening of Tracy Anderson's flagship studio in L.A., Paltrow recalled one incident in particular, when she was trying on bathing suits with a pal and received a rather unusual compliment about her figure.

"I said, 'You know, this isn't so bad for 40, right?'" Paltrow mused of her butt. "And [my friend] goes, 'It's not so bad for a 22-year-old stripper!'"

Prior to going full-force with celeb trainer Anderson's workout regimen, Paltrow claimed she was convinced that there was no way she could change her rear. "Oh, I knew it would never change!" she told reporters. "I had exercised before I had met her … I had done Ashtanga yoga and pilates and I [ran] and I thought I was fit, you know?"

But, Paltrow said, Anderson convinced her that though she was in good shape, she could transform her figure completely through the rigorous routine.

And that hard work clearly paid off! At Thursday's big event -- also attended by Kim Kardashian and Stacy Keibler -- the Goop founder wowed on the red carpet with a youthful, bright magenta Victoria Beckham dress with a black zip down the back that showed off her shapely legs and figure. The 40-year-old mother of two paired her dress with a pair of black-and-neon orange Michael Kors heels.

Paltrow added that she always pushes herself to do the workouts every day -- no matter what.

"I just sob and then kick and scream and then I just force myself to do it," she said. "I just got obsessed. When you see results like that, I started following everything she said and she completely transformed my body and I'm so grateful."
