It’s officially the end of a major chapter for Kevin Costner and Christine Baumgartner, who recently finalized their divorce. The case is complete, according to the state of California, and the former duo is now considered two single people after 18 years of marriage.

The court documents, obtained by TMZ, show that the negotiations and settlement took nine months to work out after Baumgartner first filed for divorce in May 2023. Other than the Yellowstone star’s child support payments for their three children, Cayden, 16, Hayes, 14, and Grace, 13, the rest of the details surrounding the divorce are private. Costner is paying $63,209 per month to Baumgartner after a drawn-out court battle last summer. They also agreed to waive co-parenting classes which are normally a requirement of the state.
