Kevin Costner and Christine Baumgartner are calling it quits.
Former model and handbag designer Baumgartner filed to dissolve their 18-year marriage on Monday.
“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 “Yellowstone” star confirmed to The Times.
“We ask that his, Christine’s and their children’s privacy be respected as they navigate this difficult time,” the rep added.
According to TMZ, Baumgartner, 49, asked for joint custody of their three children: Cayden, 15, Hayes, 14, and Grace, 12. Costner responded to the petition on Tuesday, also requesting joint custody of the children.
Baumgartner and Costner reportedly met on a golf course in the 1980s when Costner was rehearsing for his role in the 1996 film “Tin Cup.” The actor was married to his first wife at the time and didn’t start dating Baumgartner until 1999.
The couple split briefly in 2003 — Baumgartner wanted to have children and Costner wasn’t sure he should have more — but the two ultimately worked it out, tied the knot in Aspen, Colo., in 2004, and welcomed three children over the next several years.
This is the second divorce for 68-year-old Costner. The “Dances With Wolves” star was previously married to Cindy Silva. Their 16-year marriage ended in 1994, and according to Forbes, the divorce was one of the most expensive in Hollywood history, with Silva awarded an $80-million estimated settlement.
According to TMZ, Baumgartner is not asking for spousal support. Costner’s response, filed by divorce attorney to the stars Laura Wasser, says, “Spousal support to be payable to petitioner pursuant to the terms of the parties’ Premarital Agreement.”
Which basically means: A prenuptial agreement was signed.
