Kate Bosworth claims she can’t remember shooting her sex scene in upcoming movie 21 – because she was so drunk.

The actress reveals that she and co-star Jim Sturgess “decided to have a couple of drinks, loosen up and go for it” when it came to getting intimate in the casino flick.

Sturgess describes the unfortunate end-result to People: "We were on Grey Goose, I think. It was brilliant for about half and an hour.

"As we continued to drink ... it just became sloppy and messy. I couldn't stand up at one point."
