PETA Unveils 2012’s Sexiest Vegetarians, Jessica Chastain and Woody Harrelson Top The list!

Jessica Chastain and Woody Harrelson battled it out with some of Hollywood's most resolute vegetarians, and gave them each the one-two-punch to arise as PETA's sexiest. Who says being a herbivore doesn't have its perks?

Previous winners include: Michelle Pfeiffer, Ellen DeGeneres, Anne Hathaway, Ben Stiller, and Joaquin Phoenix.

Chastain has followed her strict diet for 15 years. "I don't want to torture anything," she told the press. "It's about trying to live a life where I'm not contributing to the cruelty in the world. While I am on this planet, I want everyone I meet to know that I am grateful they are here."

It must have been difficult for the flame-haired actress to achieve her bounteous curves for the highly acclaimed movie, "The Help." She reportedly added 15 pounds to her slender frame, not an easy task for a non-meat-eater. Her secret weapon? Soy of course!

"Soy helps you become curvy because it has estrogen in it. she revealed, "So what I would do-and this is really gross-is buy cartons of soy ice scream, microwave it and drink it. It was disgusting, [but] wait till you see my boobs in the movie." The woman obviously takes her craft seriously. We sure can't tease her about that.

To think of it, there hasn't been a time when Woody Harrelson hasn't been in tip-top shape, and now we know we can attest his toned physique to veganism. This raw food enthusiast has been a vegan for nearly three decades. The turning point for "The Hunger Games" actor was when he realized that dairy was the main source of his skin issues. "I was on a bus and some girl sees me blowing my nose, I had acne all over my face, which I'd had for years and years." Harrelson told Esquire Magazine. "And she's like: 'Hey, you're lactose intolerant. If you quit dairy, all these symptoms you got will be gone in three days.' I was like 24. And I was like, No way. But three days later: gone."
