Kevin Earl Federline, often referred to, and also known as
K-Fed, is an American dancer, actor and DJ. He is known for his two-year marriage to American singer Britney Spears, for whom he was previously a backup dancer, and the child custody battle that followed, which earned significant media coverage. His popularity led to him releasing his critically panned debut album
Playing with Fire in 2006, which is commonly considered to be one of the worst albums ever released. He has since made a number of television and film appearances, and also worked as a DJ.
