The "One Tree Hill" stars fell in love on set in 2003. They wed two years later in April 2005, but separated after just five months. Chad didn't take any time rebounding. Before they were officially divorced in December 2006, he was already engaged to another woman. Sophia wasn't scared off of dating her co-stars, though, and went on to date two more from "One Tree Hill," James Lafferty and then Austin Nichols. "Sophia and I are both professional and mature enough to get through it ... and now it's just easy," Chad later said. "We're just friends." The actor left the show in 2009 during its sixth season.
