19 Celebrity Mistresses Who Became the Main Squeeze

There's nothing that new about a nanny scandal, but most celebrities who have hooked up with the help didn't exactly go on to marry them. Such was the case for Ethan Hawke, who was allegedly cheating on then-wife Uma Thurman with their children's babysitter, Ryan Shawhughes. Ethan and Uma separated in 2003 amid rumors of his infidelity, and Ryan and Ethan tied the knot in 2008. They have two daughters together.
