Kerry Washington is tired of playing the good wife. “I’m always the woman whose husband is sleeping around, says the star of Ray and The Last King of Scotland.

“I can’t do that anymore. I need to be one of those other girls!”

She’s getting her wish in the comedy I Think I Love My Wife (out March 16), in which she plays a vixen who tempts a married father of two (played by Chris Rock who wrote and directed the film).

Kerry Washington told Us Weekly how she prepped to play a sexpot:

Did you lose a little weight for the role?

Actually, Chris had me gain weight. He wanted that va-va-voom. I don’t know how much, though. I don’t weigh myself. My trainers just had me focus on being muscular. And I took a little more freedom with food.

What does your workout consist of?

Mostly just cross-training, a lot of cardio work and strength-training. I have a trainer on each coast. They are like my bicoastal gods of health.
