Costner and the handbag designer tied the knot in 2004 and share three children — Cayden, 16, Hayes, 14, Grace, 13.

Since Baumgartner filed for divorce in early May, she’s argued the terms of their prenup, asked the court for over $150,000 per month in child support to offer their kids a “comparable” lifestyle to the one they share with their father, petitioned for the actor to pay her legal fees, and at one point, refused to vacate the lavish home she shared with Costner.

As OK! previously reported, an insider claimed that despite winning several of their court battles, the Tin Cup star “resented” having to pay Baumgartner “even a nickel.”
