Kevin Earl Federline (born March 21, 1978), also known as K-Fed, is an American dancer, actor, and DJ. He is known for being the ex husband of singer Britney Spears and the public child custody battle that followed their divorce. In 2006, Federline released a debut album, Playing with Fire, which was panned by critics as one of the worst albums ever released.
