Kate Bosworth has revealed that she and her ‘21’ co-star Jim Sturgess got drunk to do their sex scene for the movie. She says she and Sturgess “decided to have a couple of drinks, loosen up and go for it.” Sturgess said they drank vodka but soon became too drunk to even stand up. “We were on Grey Goose, I think. It was brilliant for about half an hour,” he explained to People magazine. “As we continued to drink…it just became sloppy and messy. I couldn’t stand up at one point.”
