Kevin Costner’s estranged wife claims actor’s net worth quadrupled to $400M

More money, more problems.

Kevin Costner’s estranged wife, Christine Baumgartner, claims the actor’s net worth quadrupled to $400 million over the course of their marriage.

According to TMZ, the handbag designer claims in legal docs that the “Bodyguard” actor disclosed that he had $102,716,000 in assets in 2004 when they signed their prenup.

Now, as the couple goes through their messy divorce, Baumgartner alleges Coster is worth close to $400 million — with about $24 million in cash.

In a court filing obtained by People, the mom of three accused the Oscar winner of “withholding” evidence of his finances.

Baumgartner’s attorney has asked the court to have Costner show documents related to his business ventures.

The lawyer claims the “Yellowstone” star has been “stonewalling” by not divulging information ahead of their scheduled child support hearing next week.

Additionally, Costner claimed in new court docs that he did not have an affair but “does not know for a fact” whether his estranged wife did.

His response came after Baumgartner’s attorneys asked him to provide documentation regarding his finances, including “expenses paid by you, or any person at your request or on your behalf, relating to any extramarital romantic relationships.”

The dad of seven‘s legal team objected to the requests, writing that it is “propounded only for purposes of harassment, is overbroad as to time period and subject matter, burdensome, oppressive and impermissibly compound.”

The lawyers argued in court docs obtained by People, that Costner “does not know for a fact if [Christine] engaged in any ‘extramarital romantic relationships’ before separation and, if so, whether she spent any of his money or charged any expenses in furtherance of her affair(s) on credit cards he paid.

“[Kevin] has no responsive documents for ‘extramarital romantic relationships’ in which he engaged because he engaged in none.”

Baumgartner, 49, filed for divorce from Costner, 68, in May after 18 years of marriage. Since then, the estranged spouses have been intertwined in a contentious divorce battle.

In July, a judge ruled that the “Hidden Figures” star had to pay his estranged wife $129,755 per month in child support for their three kids — though she originally asked the court for $248,000 a month.

He was also ordered to cover $200,000 in attorney’s fees and $100,000 in forensic costs.

The judge also ruled that the exes had to uphold their prenup, which required Baumgartner to move out of their shared family home by July 31.
