Kevin Costner Accuses Estranged Wife of Spending Nearly $100K of His Money on Divorce

Kevin Costner has accused his estranged wife, Christine Baumgartner, of spending nearly $100,000 of his money on their divorce. Us Weekly reports that the Yellowstone star made the claims in new court documents, wherein he alleges Baumgartner "has withdrawn from my bank account and charged on my credit card a total of $95,000, payable to her divorce attorneys and forensic accountant" since April of this year. Costner also accuses Baumgartner of spending the money "without any prior notice" to him.

Baumgartner, 49, filed for divorce from Costner, 68, last month, citing irreconcilable differences and listing the date of separation as April 11. She also requested joint custody of their three teenage children: Cayden, Hayes, and Grace. In his legal response, Costner also cited irreconcilable differences and asked for joint custody of their kids. PEOPLE previously noted that Costner's filing mentioned a prenup, which is apparently referenced due to potential issues of spousal support, properties, and legal fees. This comes decades after an $80 million divorce from his first wife Cindy Silva, whom he was with from 1978 until 1994. Costner and Baumgartner had been together for 18 years, having married in 2004.

Per a source who spoke with PEOPLE, the cause of the split had a lot to do with Costner's work schedule, which has been very demanding and put a strain on the couple's relationship. The insider added that the actor "knew" his wife was "unhappy." Despite this fact, the divorce filing was said to be an unexpected "unpleasant surprise."

"Christine wants them to spend family time at their Santa Barbara home. During filming, Kevin is not around very much. His absence has been very hard for her," the source said, later adding that one of Costner's newest projects was a major catalyst in their division. "Christine doesn't want him to throw himself into another project. He has been obsessed with filming Horizon since last year. She wasn't happy about it." Horizon is a movie that Costner has been developing. Some reports have indicated that the passion project led to Costner pulling away more from his hit Paramount Network series Yellowstonewhich has now been canceled.

PEOPLE goes on to quote a separate source saying that "at times" Costner's "career has taken precedence over his home life." The second insider added, "Kevin hasn't been home very much for quite some time due to filming, the popularity of Yellowstone, and the time necessary for his other projects. He has been in demand." They finally said, "All of this success and excitement over the new project probably took his attention away from his family more than he realized. Since it didn't look like that would change and likely could get worse, it caused tension at home."
