It’s Splitsville for Billy Joel and his wife Katie Lee. The couple announced today that they are separating after five years of marriage. “Billy and Katie remain caring friends, with admiration and respect for each other,” the couple’s publicists said in a statement. Lee, who is best known for her season-long stint as the host of Bravo’s Top Chef, was Joel’s third wife. She followed model Christie Brinkley. No word yet on whether Joel and Lee will divorce, but perhaps if they do it’ll give the Piano Man a crop of new material to pull him out of his years-long music hiatus.
