Britney Spears is rumored to have asked her ex-husband Kevin Federline to move back in with her. According to reports, the singer might be considering to give Kev-F a new chance. An insider says. "Kevin has been staying over a lot but I don't think it will be long until they are living together full-time again. They have slipped back into their old relationship really easily." "Kevin is excited about living with Britney again because he finds it tough being a single dad. She is thrilled because she can have her kids back and a relationship with someone she trusts," added the source. Meanwhile, Britney’s 'Womanizer' music clip has won as Fuse's Best Music Video of 2008.
