10. Woody Harrelson
As another actor to win PETA’s Sexiest Vegan in 2012, Woody Harrelson is an outspoken environmentalist and hemp activist. The star of Zombieland and Hungergames has also teamed up with PETA on a bunch of projects, including the release of research chimpanzees. He’s been vegan ever since he launched into his acting career in his mid-20’s in New York. The reason? Being diagnosed as lactose-intolerant by a woman on the bus that was talking to him about his tummy troubles. Life is funny like that.
