Kevin Costner’s wife, Christine Baumgartner, has filed for divorce.
According to TMZ, the designer filed to end their 18-year marriage on Monday, citing “irreconcilable differences.”
In her filing, Baumgartner, 49, asked for joint custody of their three kids: Cayden, 15, Hayes, 14, and Grace, 12.
She, however, did not ask for spousal support as TMZ reports that there is a prenup in place.
“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,” a rep for the “Bodyguard” actor, 68, confirmed to the outlet.
“We ask that his, Christine’s and their children’s privacy be respected as they navigate this difficult time.”
Costner then responded to his estranged wife’s petition on Tuesday by also asking for joint custody of the children.
Page Six has reached out to Costner’s rep but did not immediately hear back.
Baumgartner and the “Yellowstone” star began dating in 1999, shortly after Costner split from Bridget Rooney, with whom he shares son Liam, 27.
After a brief breakup in 2003, the handbag designer and Costner reunited the following year and tied the knot in Aspen, Colo.
They welcomed their oldest son, Cayden, in May 2007 and their second son, Hayes, in February 2009.

During the height of the COVID-19 pandemic, Costner gushed about how the lockdown made their relationship stronger.
“Our partnership has really come into focus about what we do for each other and how we deal with our family,” he told People in June 2020. “Our house is like a river: You’ve just got to get into the flow of it. And whatever you thought it was going to be, maybe it still can, but it’s going to have to work with what the day brings.”
The “Hidden Figures” star was previously married to Cindy Costner, however, they split in 2004.
They also share three kids together: Annie, 39, Lily, 36, and Joe, 35.
