Kristen Bell In 'Shape': Dons Bikini, Talks Diet (PHOTO)

Kristen Bell covers 'Shape' magazine and inside she talks about being a homebody with fiance Dax Shepard and shares fitness tips ("If I can burn 10 calories by avoiding the elevator, I'm all for it. More flights of stairs means I can eat more candy!")

Kristen, a vegetarian, grows her own organic vegetables but insists she enjoys the occasional splurge.

"I've learned I don't really feel well after I eat it but I also know that devouring a whole cheesecake with my girlfriends can feel incredible!" she says. "I'm always going to be the kind of person who treats myself."
