Some big-name stars are giving it all up – meat, that is. Celebs like Alicia Silverstone, Natalie Portman, Alec Baldwin, Anthony Kiedis, Forest Whitaker, Sir Paul McCartney, and Woody Harrelson, are all vegetarians, refusing to eat meat and fish for ethical, health, and environmental reasons. Some celebs have even put their money where their meat-free mouths are, posing naked in ads for People for the Ethical Treatment of Animals to draw attention to the cause. The PETA ads have become so controversial and well-known, the campaigns will be featured on this week’s Top 20 Celebs Gone Good on VH1.
