Christine Baumgartner, Kevin Costner's estranged wife, appeared in a Santa Barbara, California, courtroom Wednesday as a judge ruled on a tentative child support agreement for the couple.

The "Yellowstone" actor will pay the former purse designer $129,755 per month in child support for their three children. 

Baumgartner initially requested $248,000 monthly in support or "in the alternative, at the guideline rate of $217,300 per month, payable on the first day of each month." Costner was offering $51,940 per month.

Judge Thomas Anderle granted an evidentiary hearing, and pending the hearing, Costner and Baumgartner will each be required to pay 50% of their three children's health care expenses, sports and extracurricular activities.

Baumgartner appeared before the judge wearing a black cardigan with a silky blue blouse and black slacks. Her legal team, including attorney John Rydell and Marisa K. Beuoy, spoke on her behalf. Susan Wiesner dialed in via Zoom.

Costner's representation, which included Laura Wasser and Jacqueline Misho, appeared in court on behalf of the "Tin Cup" actor who is on vacation with his children, per previous court documents.

Rydell suggested the court combine already established November trial dates regarding the validity of the pre-marital agreement (PMA) to now also include arguments in the child support ruling.

Misho argued in court that the issue with the PMA and child support arrangements "do not coincide in any way."
