Kate Bosworth was rockin' yet another all black ensemble leaving her hotel in NYC yesterday. She's been hard at work promoting 21 both on and off the red carpet this week, and even revealed a little secret about her love scene with her co-star Jim Sturgess. She said, "We were both so drunk. Jim and I became such good friends, we decided to have a couple of drinks, loosen up and go for it." She and Jim did seem a little cozy on the red carpet, so her boyfriend James would probably prefer that Kate doesn't remember much of her steamy scenes. The movie hits the theaters today, so now she can just sit back and watch the box office to see if all her hard work paid off. Good news for Kate — our girl Buzz thought the movie was a good time.
