PICTURES: Wow! Wendy Williams Poses Nude for PETA

Hot talk? Hot bod!

The outspoken Wendy Williams lets her figure do most of the talking in a startling new campaign for PETA. The latest celebrity model to bare her body for the organization's iconic "I'd Rather Go Naked Than Wear Fur" campaign.

Launching a new national campaign on Wednesday Nov. 28, the talk show host, 48, was on hand to present her huge billboard in NYC's Times Square; in the shots, Williams wears nothing at all, with her toned figure concealed only by her long, flowing hair.

"We should all try to be comfortable in our own skin and let the animals keep theirs," said Williams in a statement. Williams used to wear real mink and fox, but changed her mind when she learned how animals are brutalized for their furs.

This holiday season, Williams will also encourage her fans to donate used fur coats to PETA -- with the aim of donating the coats to the homeless and victims of Hurricane Sandy.

Williams joins the ranks of other stars who've graced PETA's "Go Naked" campaign, including Eva Mendes, Christy Turlington, Taraji P. Henson and others.

Gaunt Matthew McConaughey: "I'm Not Being Starved" for Movie Role

Matthew McConaughey -- or what's left of him -- is perfectly healthy, thank you very much.

The 42-year-old actor is currently filming The Dallas Buyer's Club, in which he plays Ron Woodruff, a real-life drug addict in the 1980s who contracted HIV and became one of the first-ever AIDS activists. To get into character for the role, McConaughey has been dieting down his muscular frame to skin and bones.

"I'm a little more streamlined," he told the Daily Beast on Nov. 27 of his nearly 40-pound weight loss.

That's an understatement. The usually buff Magic Mike star -- now just 143 pounds -- has set the Internet abuzz with worry in recent months thanks to his gaunt, frail appearance. But he insists there's no cause for concern.

"I feel fine. I really do," he told the site. "I got the means to lose the weight in a really healthy way. I'm eating fresh fish. I'm just eating small amounts. I'm not being starved...I'm taking care of myself."

"I've been checked. My levels are fine. I'm as healthy as can be," he added. "The real health challenge is when you put [the weight] back on...You can't just start eating cheeseburgers and ice cream. Your body will go into shock, and it just won't work."

Learning about how his body does work has been something of a "spiritual journey" for the soon-to-be father-of-three. (McConaughey and wife Camila Alves have two kids, Levi, 4, and Vida, 2, with a third on the way: The pregnant model, 30, is currently in her third trimester.)

"It's really been enlightening to understand my anatomy," he said. "I don't have the leverage I used to. I have body soreness."

That said, the physical changes are just one part of the actor's overall transformation.

"I'm playing a guy who was sick and would have loved to have been healthier but wasn't," he told Us Weekly in August. "For me, it's more of a mental thing than a physical thing."

Katy Perry: I Feel Fat Without Spanx!

Katy Perry has been called "The First Lady of Hot" by Maxim, but she doesn't always feel worthy of the title.

Us Weekly caught up with the "Part of Me" singer at the Nov. 28 UNICEF Snowflake Ball in New York City, where she and other celebs including Selena Gomez, Uma Thurman, Tony Bennett and Kelly Ripa walked the blue carpet and helped raise money for UNICEF'S lifesaving children's programs.

The pop star, 28, was stunning in a tight, floor-length, semi-sheer navy Naeem Khan dress with a matching cape, Guiseppi Zanotti heels, a Judith Leiber clutch, and Lorraine Schwartz jewels -- but she admitted she didn't feel as good as others thought she looked.

"I feel like my [fat] is sticking out so bad right now," she confided in Us at the bash. "I almost always wear [Spanx], but not tonight, and I feel it pushing out, making me look fat."

"I like to say I run on the elliptical for 30 minutes watching CNN, but I don't do it often enough," she added. "So I'm just like, 'Oh, I guess I'm not fitting into this Lanvin dress for these couple of months.'"

Perry may not always love her curves, but plenty of other people do -- including on-again boyfriend John Mayer, who recently accompanied the singer on a romantic tour of the Old Mission in her hometown of Santa Barbara, Calif. The two have also been spotted packing on the PDA at several Hollywood hot spots.

"They were in their own world," a guest at Perry's October birthday bash told Us of the couple, who reunited in September after briefly separating in August. "She didn't even talk to her friends much. It was just her and John. She's obsessed with him."

Jessica Simpson Pregnant Again: Weight Watchers Speaks Out

It's safe to say soon-to-be second time mama Jessica Simpson's priorities have shifted a little bit as of late.

Since welcoming baby Maxwell on May 1 (her first child with fiance Eric Johnson), designer/actress/singer Simpson, 32, has been focused on her bonding with her little one -- and slimming down after her much-discussed 70-pound pregnancy weight gain with help from Weight Watchers (plus some extra motivation in the form of a rumored $4 million paycheck from the company.)

So what does her surprise second pregnancy -- as reported exclusively in the new Us Weekly, out now -- mean for her deal? The brand is refusing to, well, weigh in.

"Any questions related to Jessica's personal life can only be answered by her team," Stephanie Schulman, Weight Watchers' public relations manager, told E! News Wednesday. "We do not disclose financial details about our relationships with any of our ambassadors."

A rep for Simpson had no comment about the Fashion Star mentor's latest baby joy. Meanwhile, a source close to the Texas native tells Us she "really is overjoyed!"

PICTURES: Diane Kruger Reveals Sexy Bikini Body on Vacation With Joshua Jackson

Caliente!

Diane Kruger showed off her slim, toned physique -- check out those abs! -- in a teeny grey bikini while vacationing with boyfriend Joshua Jackson in Los Cabos, Mexico. The couple spent the holiday weekend soaking up the South of the Border sunshine and lounging poolside at their hotel.

Kruger, 36, looked resort-ready in her bikini, red-rimmed shades, and a straw-colored fedora, while her Fringe actor beau, 34, relaxed in black board shorts with blue and green stripes.

The affectionate twosome have been together since 2006 -- but according to Jackson, their relationship almost never got off the ground.

"Our first date was a miserable one," the Canadian-born Dawson's Creek star told Us Weekly in July of his initial attempts to woo the German actress, explaining how she had an allergic reaction to one of the flowers in the restaurant where they were eating.

"And when I get nervous, you might have noticed that I talk a lot. So I just chewed her ear off for an hour and a half. It was amazing," he joked. "I'm surprised she ever called back."

Jackson previously dated his Dawson's Creek co-star Katie Holmes; Kruger was married to French actor/director Guillaume Canet from 2001 to 2006.

"I'm 20 lbs. heavier than I was when we started dating," she told InStyle earlier this year. "And now we always have great wine, and I can tell the difference. So I told him, 'You ruined my life because I can't go to a friend's house and drink cheap wine anymore.'"

Though she's gained a bit of love weight, the blonde Safe Haven beauty isn't a fan of depriving herself of the food she loves.

"It's what you want to feel on the inside, not necessarily what you want to look like on the outside," the actress told Women's Health in 2011. "Now if I want something, I'll have it and I won't feel guilty. Then the next day I won't crave it."

See Beverley Mitchell's First Baby Bump Picture

It's Beverley's baby bump!

Beverley Mitchell kicked off the holiday season with a bulging belly of the pregnant kind.

A few weeks after announcing her first-ever pregnancy, the Seventh Heaven actress, 31, debuted her baby bump via WhoSay on Thanksgiving Day.

“Happy Thanksgiving! Here is my first belly pic! 21 weeks,” says the actress. “Watch out! The belly is getting bigger!”

Due in April 2013, the baby-to-be is the first for Mitchell and accountant husband Michael Cameron. After dating for five years, she and Cameron, 32, got engaged in 2006 and tied the knot in October 2008 in Ravello, Italy; among the bridesmaids was her former costar  Jessica Biel, who loved the wedding locale so much that she married Justin Timberlake in the same region four years later.

"Can't wait to share this journey with you. We are so thrilled to become parents," Mitchell wrote when she announced her pregnancy earlier this month. "It couldn't be a more exciting time! Thank you for all the well wishes!"
