Jessica Biel
Jessica Biel is known for her honesty about her hard workouts and clean eating, but even she admits in an interview with W magazine that sometimes it goes a little too far. "I know. I think I need to destroy my reputation. This whole I'm outdoorsy, I'm really healthy—it's too squeaky-clean [laughs]. That's going to be my new thing: Go dark and unhealthy. It's time to be very, very bad."
