Kate Bosworth can "drink anyone under the table", according to her '21' co-star Josh Gad.

Josh claims the 25-year-old actress - who has previously dated Orlando Bloom and actor Matt Czuchry - is "fun and crazy" and can definitely hold her alcohol.

He told Marie Claire magazine: "Kate can literally drink anyone under the table. Get a couple in her, and she's definitely a very fun and crazy girl. We went out to a pub on St. Patrick's Day once. Not only did she pick the place, but she picked the rowdiest place, where everybody and their mother came."

"And it's like, 'OK, she's one of us!' But Kate is always one step ahead of you. She had a blast, and everybody was just enamored of the fact that there's a superstar singing and dancing and going nuts. But she was also the first one to be like, 'OK, I'm out of here.'"

In new movie '21', Kate plays one of five Massachusetts Institute of Technology (MIT) students who train to become experts in card counting in order to take Las Vegas for millions of dollars.

The 'Superman Returns' actress recently revealed she was forced to have blackjack lessons for the role, adding: "We had to take classes in blackjack. And ironically, considering this film is about card counting, math has always been my worst subject!"
