Cameron Diaz in Elle UK December 2012 Magazine Pictures

Cameron Diaz slipped into a little white Chanel dress for the December cover of Elle UK. The magazine caught up with Cameron at Guy Ritchie's London tavern, The Punch Bowl, to chat about her acting career and her forthcoming film Gambit, in which she stars with Colin Firth. Like her best friend Gwyneth Paltrow, Cameron's also trying her hand at publishing. She talked with the magazine about why she decided to share her personal health, fitness and lifestyle tips in a book. Here's more from Cameron's interview:

• When asked what burns more calories — 30 minutes of dancing or 30 minutes of sex: "Depends on what kind of sex you're having. Try 'em both! Do them both on the same day, that's what I say!"
• On what she would do if she wasn't acting: "I have no idea. That's why I'm so grateful for it [acting success]. It's the only thing that I know how to do. I do think about it all the time — what would have happened had I not just found my way out from that? But I think you always find your way out."
• On her forthcoming food and fitness book: "It's not about what I eat or do what I do. It's really about the information, so that young girls and women can look at it and make their own choices. I'd hate to give them guidelines of what I do. My hope is that I give them all the information so that it doesn't matter what I or other people do . . . I'm excited about my discipline [which revolves around] a protein, a grain and a green . . . I want to be disciplined. It's not a limitation to me; it opens up my life to so many opportunities."
