Repeat Offender(s): It's believed that Murray had begun seeing Kenzie Dalton, a former cheerleader extra on the set of "One Tree Hill," a few months after his marriage to Bush. He and Dalton later became engaged. After her divorce, Bush briefly dated her "Stay Alive" co-star Jon Foster and "One Tree Hill" co-star James Lafferty. She is currently with "OTH" co-star Austin Nichols although they did not meet on set.
