Before K-Fed was knocking up Britney, he was knocking up Shar Jackson. Mr. Federline was so busy getting busy, he seemed to be having trouble making rent. A rent check from Kevin has made its way onto eBay -- with INSUFFICIENT FUNDS stamped on it! Classy!
Things picked up after he hooked up with Britney; enough that someone had the neat idea to get Kev to autograph a microphone. He signed it, prophetically, "America's Most Hated."
