If there's anything that can cause a traffic jam even by New York City standards, it's a naked Wendy Williams in Times Square. As a crowd of cheering fans and snapping flashbulbs drowned out the honking taxis, a fully clothed Wendy unveiled her much-anticipated nude anti-fur ad for PETA:

The talk show host used to wear real fur made from foxes and minks but stopped after she learned from PETA how animals raised for their fur are electrocuted, bludgeoned, or skinned alive. Now, she knows that it's much better to bare skin than to wear skin. "I'd rather go naked than wear fur—it's very sexy," she purred during her photo shoot with top celeb photographer Aaron Cobbett.

Wendy hopes her actions will inspire other fur-wearers to shed their skin as well. And she already has the perfect idea for what they can do with those tacky, cruel coats: Donate them to PETA, and we will distribute them to people who are homeless because of Hurricane Sandy.

Helping people and animals—seems like the perfect reason for witty Wendy to get a little cheeky.

What's better than T-shirt time? "No T-shirt" time! And that's exactly what the throng of Jersey Shore fans got outside MTV's Times Square studios when Mike "The Situation" Sorrentino revealed his new PETA ad encouraging everyone to spay and neuter their animals.

Fans who couldn't make the unveiling still got to see Sitch's sweet tweet that revealed his ad and gave some love to PETA. And he wasn't the only one turning Twitter into an animal love-fest this week. Check out what these other celebs were doing to help with PETA campaigns:

Morrissey sings about how "Meat Is Murder," so, of course, he doesn't want any dead bodies around him when he's performing. For his appearance on The Colbert Report, Morrissey insisted that the entire building be meat-free for the day. And when, in true Colbert fashion, Stephen tried to rib Moz about his morals, the PETA pal had some zingers of his own ready. "Animals are nicer than humans," he deadpanned. "If you stick your grandmother in an oven, she will probably be tasty. But is that any reason to eat your grandmother?"

James Cameron might be about to make a titanic impact on the way the world eats. The director and newly minted vegan is challenging environmentalists to adopt a plant-based diet to save the planet. During a recent speech, he told the audience, "I want to challenge everybody here: If you're an environmentalist, I say, my challenge is, you can't be an environmentalist, you can't be an ocean steward, without truly walking the walk, and you can't walk the walk in the world of the future, the world ahead of us, the world of our children, not eating a plant-based diet."

And vegan Emily Deschanel is speaking up once again. Her show, Bones, dedicated another episode to animal rights, this time, to the cruelty of keeping exotic animals as "pets."
