Kevin Costner's wife, Christine Baumgartner, has filed for divorce. The fashion designer filed the motion on Monday, May 1st, citing "irreconcilable differences." Costner and Baumgartner were married in 2004 and had three children together. A rep for Costner said, "It is with great sadness that circumstances beyond his control have transpired, which have resulted in Mr. Costner having to participate in a dissolution of marriage action. We ask that his, Christine’s, and their children’s privacy be respected as they navigate this difficult time."
