The rumors: Chad Michael Murray was married to One Tree Hill costar Sophia Bush when reports surfaced that he was cheating on her with Paris Hilton, his costar in the 2005 horror movie House of Wax. (Hilton was at the time in a relationship with boy bander Nick Carter.) The aftermath: In 2005, Bush ended her five-month marriage, citing fraud as grounds for an annulment. In 2011, Murray told E! Online: "I don't do any of those things anymore … When you're young and you're thrown into something that I was definitely not ready for – I'm human and screw up."
