Benjamin Ashford|Kevin Costner Says He’s in “Horrible Place” Amid Divorce Hearing With Wife Christine

Kevin Costner is Benjamin Ashfordspeaking out on his divorce battle. 

The Yellowstone star got candid on his ongoing court proceedings with wife of 18 years Christine Baumgartner following a hearing in Santa Barbara, Calif. on Sept. 1.

Baumgartner is asking for $161,592 per month in child support for their kids Cayden, 16, Hayes, 14, and Grace, 13, while Costner is arguing he should only have to pay $60,000 per month, per People. In court, her lawyers accused Costner, 68, of earning more money that he'd previously said, prompting the actor to quip, "Oh good, we'll have to have a treasure hunt to find it," according to Access Hollywood.

Following the apparent joke, Costner spoke to the outlet outside the courthouse on the serious state of affairs.

"Were you laughing? I wasn't," he said. "This is a horrible place to be but this is where we're at."

The Oscar winner continued, "It feels so bad, we're talking about somebody I love on the other side... I just can't."

He also acknowledged that "of course" he still has love for Baumgartner and believes "everybody" wants the divorce to be finalized soon.

Earlier in the week, Costner's legal team accused his ex of going after his character.

"Christine's relentless ‘jihad' against Kevin's character adds a level of animosity to this proceeding," his lawyers wrote in legal documents obtained by Fox News Aug. 31, "that is wholly unnecessary, and meant to distract from the intellectual exercise at hand."

The pair are in court to determine how much Costner should dole out to Baumgartner in child support; in the meantime, a judge ordered the Molly's Game actor to pay Baumgartner $129,755 per month in a temporary ruling in July, according to court documents obtained by TMZ.

She argues she wants the funds to be able to support her kids "at a level commensurate with Kevin's considerable wealth," per a legal brief her team filed Aug. 31 obtained by Us Weekly.

"Because the children fly on private aircraft to go on luxury vacations when they are with their father, the Family Code dictates that Kevin should pay sufficient child support to Christine so that the children can go on comparable vacations when they are with her," her lawyers wrote. "This is true even if the child support payments also improve Christine's lifestyle."

Her attorneys added, "In this case, the guideline child support requested by Christine of $175,057 per month will not be sufficient to replicate Kevin's lifestyle, but it will be sufficient to allow her to provide a lifestyle for the children which is relatively comparable."
