Bosworth got drunk for '21' love scenes

Kate Bosworth has admitted that she got drunk while filming love scenes in new movie 21.

The actress said that she became close friends with co-star Jim Sturgess and confessed they "became sloppy and messy" after consuming large amounts of vodka on set.

She told People magazine: "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.

"We were on Grey Goose, I think. It was brilliant for about half an hour. As we continued to drink...it just became sloppy and messy. I couldn't stand up at one point."

Bosworth plays student Jill Taylor in the movie, which is adapted from Ben Mezrich's best-selling book Bringing Down the House: The Inside Story of Six MIT Students Who Took Vegas for Millions.
