Kevin Federline

When Kevin Federline was a back-up dancer for Britney Spears with an eight months pregnant wife at home he decided to dump his former life, including his wife and unborn child, to run off with Britney. In two years Britney and Kevin welcomed two boys into their family, but their relationship soon deteriorated. Following Britney's breakdown a judge awarded Kevin custody, where he received $20,000 a month to care for the children.
