Third time's not quite a charm after all. Rumors of Billy Joel's third marriage ending are true, a rep of the musician confirmed to the NY Post. Katie Lee Joel, his 27-year-old ex-wife-to-be, has been seen around town many times with designer Yigal Azrouel, though there's no official word if that relationship had anything to do with the split. A rep told ET, "After nearly five years of marriage, Billy and Katie have decided to separate. This decision is the result of much thought and consideration. Billy and Katie remain caring friends, with admiration and respect for each other." The two were married for five years, and the divorce will put Joel back on the market at age 60. Meanwhile, according to a recent poll, 57% of women regret marrying their husband.
