Yellowstone actor Luke Grimes made a bold claim about his former co-star Kevin Costner after he made his exit from the popular Paramount series. Grimes spoke out about the series as it prepares to launch into its final episodes, bringing the stories of the characters that fans have followed for the last six years to their end.

To see the final episode of Yellowstone (sans Kevin Costner), you can catch it live on Sunday at 8 p.m. ET on the Paramount Network. If you are looking to go back and watch Costner, Grimes and co. working together, you can stream the first four and a half seasons of the modern Western with a Peacock subscription.

In the first photo, Costner flashes a smile while on a beach accompanied by daughters Annie, 40, Lily, 38, and Grace, 14. Also in the beach shot are sons Joe, 36, Cayden, 17, and Hayes, 15. The “Yellowstone” star stood in the middle as his kids embraced once another while posing.

In a new interview, Yellowstone star Luke Grimes threw some shade in the direction of his former costar Kevin Costner hinting at on-set drama.
