Kevin Costner and his wife, Christine, are going their separate ways after 18 years of marriage. The pair share three children, Cayden, 15, Hayes, 14 and Grace, 12. A rep for the 'Yellowstone' star announced the split on Tuesday, sharing with ET in a statement, '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.'
