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.
