Well, Kevin Costner's estranged wife, Christine Baumgartner, is demanding that he pay her nearly a quarter of a million dollars per month in child support. She wants $248,000 for all three children, again, per month, $248,000 per month, which she claims is less than the amount needed to maintain the children in their accustomed-to lifestyle. The Yellowstone star's wife also asks that he cover 100% of the private school tuition, extracurricular expenses, and health care for their now teenage kids. Earlier court docs reveal Kevin agreed to fork over about $38,000 a month in child support, cover all of their costs, contribute $30,000 per month toward a rental home for Christine, and give her $10,000 for moving costs to get out of the homes that they shared. Now, a couple of things here. Christine is throwing stones and said Kevin very nonchalantly let their kids know that they were splitting after 18 years of marriage via a 10 minute Zoom call, which she was not allowed to be a part of. And she says she was confused by his motivation to spill that news this way, especially since he was planning on being home five days later and could have done it face to face in person. And then the story I told you yesterday, that Kevin absolutely went through the roof and was so pissed off when he found out Christine was possibly hooking up with a tech mogul that was renting the guest house at one of his beach properties. TMZ caught up with that guy at Starbucks yesterday.
