Kevin Federline claims to have made less than $10,000 from his music career since May, evidently surviving off child support and that Super Bowl ad. Yesterday, Federline’s lawyer released financial documents in court as part of his custody battle against Britney Spears. Despite some big, big tippin’ ($2,000 on a $365 meal bill at a strip club!), Federline made only a fraction of the $74k he spent on “music production” in the same period. No word on who the fuck gave K-Fed that 10 grand. [AP]
