Brit actors Jude Law and Clive Owen were so impressed by their "Closer" co-star Natalie Portman's pole-dancing in the film, they decided to try the exotic routines themselves.
While preparing for her role as stripper Alice, Portman signed up for a series of classes to perfect her grinding moves, and her male co-stars couldn't resist having a try.
Law says, "We both had pole-dancing lessons. It's the de-riguer style of exercise now in London. It's very good for the upper thigh and the deltoid."
