Does anyone know how much Kevin Federline was paid to try to ruin Britney Spears life because we hope it was worth it. In Kevin Federline's explosive memoir, "You Thought You Knew" he writes about Britney Spears dangerous and abusive behavior towards Kevin and her two young children. He claims he's trying to save her, but her child support checks have stopped coming so he wrote this book in the knick of time! I'm Team Britney. Her life, money and relationships have all been mismanaged and we hate to see what she's become. Kevin will be a loser forever. He seriously doesn't want to work another day in his life, LOLs. Britney was paying him $40,000 a month in child support. WHY DIDN'T HE INVEST SOME OF HIS MILLIONS? He sucks.
