Michael Phelps "stars" in Entourage

Michael Phelps has become the latest sports star to make a cameo in a tv series or movie.
The 8 medal Beijing Olympic champ appeared in Entourage last night for a very, very brief scene.
He follows other sporting heroes like Karreem Abdul Jabaar, who played a pilot in Airplane, Brett Favre, who appeared in Something About Mary, Tom Brady the Patriots quarterback was in Stuck on You and Lance Armstrong, who made a hilarious cameo in Dodgeball.
