Kevin Costner and wife Christine are divorcing.
The "Yellowstone" star's representative confirmed to Fox News Digital that the couple, who have been married for 18 years, are ending their relationship.
"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," Costner's rep said.

Kevin, who celebrated his 68th birthday in January, and Christine, 49, married on his ranch in Aspen, Colorado, in September 2004. They have three children together.
He was previously married to Cindy Silva for 16 years and had two daughters and one son with his ex-wife.
Costner also has one son with Bridget Rooney.
The "Field of Dreams" star received a Golden Globe award earlier this year for his role as John Dutton in Paramount's "Yellowstone," but was unable to attend the event due to heavy rainfall and flooding near his home in California.
He shared a video on social media weeks later when he received the coveted trophy in the mail.

"We weren’t able to make it to the Golden Globes because of the flooding we got cut off … and we felt so horrible about that and there was just nothing we could do," he said. "We watched the time, like sand in the bottle, go out as our chances dimmed of getting there."
Costner credited Christine with making the most out of the experience by decorating their home with balloons.
"We weren’t at one of the greatest parties in the world, but we found ourselves together as a family," he said. "And my children heard my name called and they stood up and they cheered."
Paramount has yet to confirm if Costner is returning to the Dutton ranch despite the network promising a summer premiere. It's unclear if new episodes have already been filmed.
"We have no news to report. Kevin Costner is a big part of ‘Yellowstone,’ and we hope that's the case for a long time to come," a Paramount Network spokesperson told Fox News Digital when asked if the cowboy drama was coming to an end.
