Simon Cowell's last episode as a judge of American Idol will air this evening. It's the end of his era on the show after he helped launch it nine seasons ago, but he'll return to television with the American version of his hit UK program The X-Factor. This evening will be Simon's final outing at the table with Randy Jackson, Ellen DeGeneres and Kara DioGuardi, though, as they decide if Crystal Bowersox or Lee Dewyze will win. So, tell us — will you tune in for Simon Cowell's last night as a judge on American Idol?
