Britney Spears' estranged husband Kevin Federline is having another crack at stardom with a reality TV concept surrounding his life as a single dad. The dancer-turned-rapper is reportedly pitching leading US TV networks the idea - and insiders claim he's got a chance to become a star all over again. One source says, "Thanks for Britney's rehab drama and the squabble over their kids, suddenly the show doesn't seem like such a bad idea... People are intrigued by Kevin again." Federline has had several stabs at success in the past 12 months, launching a flop rap career, appearing on TV drama CSI: CRIME SCENE INVESTIGATION and even poking fun at himself in a fast food restaurant-themed commercial that aired during the Super Bowl American football final last month (FEB07).
