Cameron Diaz undergoes rigorous exercise routines to put on weight - because she'd become "really skinny" if she stopped working out.
The Charlie's Angels beauty is renowned for her lithe figure, but admits her toned torso is not down to genetics, insisting she has to work hard to ensure she doesn't fall below a healthy weight. And Diaz can't imagine life without her daily keep-fit routines at the gym.
She tells Harper's Bazaar, "Exercise for me is like eating, sleeping, and breathing. I'm consistent, and when I'm not consistent, it shows up on my body. I get really skinny, and I know it might sound like, 'Well, good for you.' But the body that people talk about is not me trying to stay slim, it's the one where I work hard to keep weight on me. Your body definitely does change."
