Woody Harrelson: Sexiest Vegetarian, 2012
According to PETA, Woody, known for his recent role as Haymitch in the blockbuster hit The Hunger Games, has been vegan for nearly three decades. He had his "aha" moment when he was trying to make it as an actor in New York: "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. 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."
