Kevin & Christine's NASTY HE SAID, SHE SAID

The divorce gets even uglier as Kevin Costner tries to curb estranged spouse Christine Baumgartner's spending!

That's some serious plastic! After Christine Baumgartner racked up more than $100,000 in legal and accounting fees, Kevin Costner canceled one of his estranged wife's credit cards and put a $30,000 limit on another. "Christine began charging large sums on the credit cards payable to her divorce attorneys and forensic accountants. She gave me no advance warning," the Oscar winner, 68, said in a June 30 court declaration, noting his future income is unsure now that Yellowstone is ending following five seasons on Paramount+. "I made the decision that there needed to be some reasonable limitation on the use of the credit cards."
