Find out the shocking ways these celebs earned their fame!

Kevin Federline

Federline can thank Britney Spears for his initial fame as he went from a backup dancer to husband (and now ex-husband, obviously) of the pop sensation in 2004. Even though they are no longer together, the couple has two sons. His only onscreen performance would be on the TV reality show Britney & Kevin: Chaotic, which aired in 2005. They filed for divorce soon after and went their separate ways. However, Federline has always stayed slightly in the spotlight after his marriage with Britney. He later married Victoria Prince and had two more children for a grand total of six.
