Sophia Bush and Chad Michael Murray
Bush and Murray met when they played high school students in the teen drama One Tree Hill in 2003. But after tying the knot in April 2005, the pair separated and filed for annulment five months later after rumors surfaced that Murray allegedly cheated on the actress with Paris Hilton. In January 2014, Bush gave a diplomatic response when a caller asked her about the split during an appearance on Bravo's Watch What Happens Live. "My mother once said to me that if you don't have anything nice to say, not to say anything at all," she quipped.
