Kevin Costner and wife Christine Baumgartner divorcing after nearly 19 years of marriage

Kevin Costner and his wife of nearly 19 years, Christine Baumgartner, are divorcing, a representative for the actor said Tuesday.

"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," Costner's publicist Arnold Robinson said in a statement.

Costner and Baumgartner, a model and handbag designer, began dating in 1998 before getting married at his Colorado ranch in 2004.
