Looks like it’s moving day at the Costner household.

Trucks were spotted outside the California estate Kevin Costner shared with ex-wife Christine Baumgartner, amid the couple’s sour split.

Baumgartner, 48, filed for divorce from the 68-year-old “Yellowstone” actor in May citing “irreconcilable differences” after an 18-year marriage.

The news comes just days before July 31, when the former handbag designer was ordered to vacate the family home in coastal Carpinteria, near Santa Barbara, by the court, as per the ex-couple’s prenup.

The separation has allegedly been exceptionally bitter, with sources saying the “Yellowstone” star has sworn to make his ex-wife’s life a “living hell.”

The Post has reached out to both Costner and Baumgartner for comment.

There have been reports the couple have been bitterly feuding over child support and their prenup — as well as Costner alleging Baumgartner has taken large sums of money and other assets behind his back.

Earlier in the month, Costner was ordered to pay Baumgartner $129,755 per month to support their three children — more than double his proposed amount of child support of $51,940 a month.

This comes after Baumgartner had deemed the latter amount “completely inappropriate,” claiming that she needed $248,000 a month in child support.

The newly-single Costner was recently spotted with his children, soaking up the summer sun in Aspen, Colo.

Costner was seen shopping for groceries with Cayden, 16, Hayes, 14, and Grace, 13 on their way from the airport. The children had been on vacation with their mother in Hawaii.
