Beyonce is on strict diet to lose the 20 pounds she had to gain to play blues legend Etta James in the upcoming film Cadillac Records. That’s not such a big deal, but she has to lose the weight fast for her next project in a psychological thriller titled Obsessed. It’s such a time sensitive issue that she even had the following stipulations at her recent interview and photo shoot with Marie Claire. “no chips, no candy, no desserts, no junk food, no fried food”.

Putting on the pounds ‘was so much fun’, she confesses. ‘But I had to lose it. I was so angry with myself. I was like, “Doh!” Why do you have to go through this?”‘ You can’t blame a girl for wishing to avoid temptation, particularly one whose living is partly dependent on her looks.’

You can read the rest of the interview here. It’s full of interesting tidbits about Beyonce’s alter ego, her decent into darkness as Etta James and who “Irreplaceable” was really about.
