Renée ZellwegerRenee Zellweger has said she believes exercise is good not only for her physical health but her for mental health too.

Speaking at the London premiere of her new film Bee Movie this week, she was annoyed when a reporter seemed to suggest she was a little too thin at the moment. She replied: “Are you telling me my curves are absent? I think I am doing very well, thank you very much.”

“I think I’m doing alright. There’s no fitness regime. There’s just a lifestyle. It involves keeping my sanity if I go to the gym, and working out the weirdness of the day.”

She added though that she was feeling heavier than normal as she walked the red carpet in a floor-length Caroline Herrera dress: “It is soaking wet. I am like a sponge. My dress weighs another six stones.”
