Movie stars Will Smith and Heather Graham had a talk show audience roaring with laughter when they showed off their rapping and yoga skills. Men in Black star Smith enlisted his 14-year-old son Jaden to perform a brief rap before bringing out two surprise guests for a rendition of the theme tune to his breakthrough TV show The Fresh Prince of Bel-Air. Smith followed up his musical offerings by helping out Graham - a fellow guest on host Graham Norton's U.K. talk show - as she showed off her yoga moves. The actress also told the audience of her experiences on the male-dominated set of The Hangover Part III, saying, "There are moments when you feel so good because there are all these guys and you get all this attention as the woman on the set. Then there are other moments when they are so bonded with all their testosterone that you feel like you are sitting in the corner." The show, which also features interviews with Bradley Cooper and Michael Douglas, is due to air in the U.K. on Friday (24May13).
