It probably didn't bode well when Ryan Adams hung up on an Australian interviewer in September who wouldn't stop asking about his marriage to Mandy Moore. Or when Adams' self-titled album from last year turned out to be "one of the more downcast, melancholic LPs in the singer-songwriter's vast catalog," in the words of Rolling Stone. This might be why: Radar reports that Adams, 40, and Moore, 30, are divorcing after six years. Moore cited irreconcilable differences when filing the papers. They have no kids. In other celeb divorce news, Patrick Dempsey—aka "Dr. McDreamy"—is splitting with his wife of 15 years, Jillian Fink, reports Page Six. They have a 12-year-old daughter and 7-year-old twins.
