Shall we call it a "One Tree Hill" tragedy? Sophia Bush and Chad Michael Murray, they first met on the WB show in 2003 and since then embarked on a romance before finally tied the knot in April last year. Unfortunately, by September the same year they parted ways.

Just now, it's been learned that Bush is seeking to annul her five-month marriage to Murray, filed papers Friday in Los Angeles Superior Court citing "fraud" as the reason for wanting to clear the relationship from the books. In fact, A fraud claim can be "difficult to prove" for State law reads that a fraudulent marriage means "the consent of either party was obtained by fraud."

And so Bush will have to prove her case to the court otherwise if a judge denies her annulment request, she can seek a divorce from Murray.
