Bosworth revealed she was so drunk while filming a steamy love scene with Jim Sturgess in 21, she can't even remember it. "We were both so drunk," the sexy 21 siren told People. "Jim and I became such good friends, we decided to have a couple of drinks, loosen up and go for it."

So what was the stars' drink of choice on the set to prepare for their love scene? "We were on Grey Goose, I think," Bosworth told People on Wednesday at the Cinema Society and Calvin Klein Jeans-sponsored screening of the film in Manhattan.
