Kevin Costner is shooting his shot in the middle of his divorce drama ... he was spotted taking some solid swings at a driving range in Utah while he shoots his latest movie project.
The actor was at BigShots Golf in St. George Tuesday night, just hours after TMZ broke the story his wife Christine's calling it quits after 18 years of marriage ... and those at the range tell us he was having a great time.
He's in the Beehive State for his new western epic, "Horizon: An American Saga," so the group he was with was likely part of the cast and crew. Kev had a pretty great swing and even appeared to be doing some coaching.
As we reported, sources familiar told us Kevin was completely blindsided by Christine's filing ... and it was devastating for him. There were internet rumors Kevin got a woman pregnant on the set of "Yellowstone," but sources close to the actor called it "total BS."
Kevin was golfing hours after he filed his response to Christine's divorce petition. As we reported, there's a prenup, he owns all of their 3 houses, and she must vacate according to the document. They have 3 kids and both want joint custody.
