Chad Michael Murray, Sophia Bush Split
A spokesperson for Bush confirmed the split, but offered no further details on the relationship between the couple, who star together on One Tree Hill.
"This is a difficult and unfortunate situation," said Bush in a statement. "I am glad this is being resolved sooner rather than later."
"I am saddened to announce that Sophia and I are separating," said Murray. "This is a very difficult time for me."
Murray and Bush exchanged handwritten vows during their wedding on April 16 at Santa Monica's Hotel Casa Del Mar before 200 guests.
The couple got engaged in May 2004 in Australia when Murray popped the question on a tennis court adorned with 20 bouquets of roses and 500 lit candles spelling out a special message for Bush.
"It's a really, really important moment for a woman, so I wanted to do what I could do to make it special," Murray said at the time.
The pair met on the set of their WB show and began dating in 2003.
