Presidential debate moderator Candy Crowley likes getting into meaty issues—but not into meat. Maybe it was her vegetarian diet that gave her enough energy to keep the candidates in line?

Newly vegan Kristen Bell doesn't miss an opportunity to advocate for animals—and she doesn't miss dairy products, either. "[H]onestly, there are so many good substitutes available now that I really don't miss anything," she told Shape magazine. Kristen also mentioned that as much as she loves sloths, she would never keep one because, she says, "I don't support the exotic animal trade."

Salma Hayek agrees. She told Jimmy Fallon, "I am completely against people having exotic animals as pets. This is completely, completely wrong." Gushing about her passion for rescue, she rattled off all the animals who inhabit her estate, adding, "See, I had no husband, no children. I only had my animals, and I'm not going to get rid of them just because I fell in love, and, you know, motherhood. "

Ben Stiller realizes that exotic animals don't belong behind bars, either. The funnyman got serious when asked how he feels about zoos, saying, "I used to be for it. Now I'm against it. I don't love zoos; I've taken my kids to them but I saw that documentary a couple of years ago, The Cove, and that affected me in terms of knowing how these dolphins get into these dolphin parks. So I stopped supporting them." What else have Stiller and his family stopped supporting? The meat and dairy industries—Stiller and his wife, Christine Taylor, are vegan and are helping their kids embrace veganism, too.

The winner of RuPaul's Drag Race, Sharon Needles, embraced flesh of the human variety for her Halloween-themed pro-vegetarian ad for PETA. Drag royalty Lady Bunny was one of the multitude of folks speaking up for animals on Twitter this week, posting her excitement about the new ad:

Leonardo DiCaprio knows that sometimes you need a little more than 140 characters, so he is devoting his Facebook page to the protection of whales, orcas, seals, and penguins. The actor asked for support for the Antarctic Ocean Alliance, which aims to create "the world's largest network of marine protected areas."

Pamela Anderson is ready to take her advocacy for horses face to face: She invited New York City Council Speaker Christine Quinn on a date! Pam is set to host a gala that will benefit the campaign to replace horse-drawn carriages with eco-friendly replicas of classic cars, and she thinks that if Quinn attends, the speaker will reconsider her support of the horse-drawn carriage industry.

Michelle Pfeiffer is known for three decades of film and television roles, Oscar nominations and a Golden Globe, her stunning and ageless beauty, and, now, her cruelty-free diet. She told Dr. Sanjay Gupta on CNN that the evidence pointing to the healthfulness of a vegan diet is so clear that "I couldn't not listen to it."

Rani Williamson, aka "Miss Maine USA," might not have snagged the tiara at the Miss USA pageant, but she captured a lot of hearts for promoting vegetarian eating.

Pink's heart belongs to her daughter, Willow Sage, whose first birthday party the singer celebrated with an adorable three-tier vegan cake shaped like baby blocks. 

The book that's veganizing the world, Skinny Bitch, will soon be veganizing the fiction section as well when the new novel Skinny Bitch in Love hits shelves.

Who is likely to be celebrating by vegetarian Fiona Apple's side when her new album comes out this month? Her rescued pit bull mix, Janet, who is her constant companion.

Sophia Bush added a new rescued pit bull mix to her family, and PETA helped her welcome little Griffin with toys, treats, and our "Mutts Rule" T-shirt. 

Leonardo DiCaprio is jumping in to save fins. The actor helped get a ban on shark-finning passed in California, and now he's set his sights on getting a similar bill passed in New York.

Supermodel and former Leonardo DiCaprio flame Bar Refaeli is catching heat for posing in fur for clothing company Bel Air, especially in light of the proposed fur ban in Israel. Honorary PETA Director Pamela Anderson sent Refaeli a letter explaining, "You probably weren't aware that numerous undercover investigations have revealed that foxes, minks, coyotes, and rabbits—and even cats and dogs—are bludgeoned, genitally electrocuted, and often skinned alive for their pelts." Pam asked Refaeli, model to model, to raise the bar on ethical fashion and dump fur.

But Refaeli insisted that there had been a titanic mistake, telling an Israeli publication that Bel Air had lied to her and said the fur was fake. Then she took to Twitter, posting, "I think its time 2 get it straight! i'm against fur! the truth of the matter is that on the shoot day i was told the fur is FAKE!"

Considering the lies that the fur industry tells about how animals are killed, it's not surprising that fur-mongers would finagle Refaeli into donning pelts.

Be a model of compassion and bar fur from your closet. Lookin' at you, Blake Lively…
