Kevin Costner doesn’t have time for the drama. Honestly, after the whirlwind that was his Yellowstone exit, you’d think the man would want to stay far away from any headlines involving the Dutton ranch. But lately, the internet has been buzzing about a supposed rift between him and his on-screen son, Luke Grimes.
The rumor mill went into overdrive after Grimes admitted in a series of interviews that he hasn't spoken to Costner since the patriarch left the show. People jumped to conclusions. They assumed there was bad blood, or maybe some lingering resentment over how the show’s final season was handled. But when a reporter finally caught up with Costner in Aspen to get the "real" story? He shut it down.
Kevin Costner Dismisses Feud Rumors With Luke Grimes and Moves On
While walking through the snowy streets of Aspen in late 2024, Costner was approached by a reporter asking about his relationship with Grimes. The response was classic Costner: brief, firm, and slightly enigmatic. When asked if he had spoken to Luke or if there was any truth to the tension, he basically said he wasn't thinking about it.
"No. We're done talking," Costner told the photographer while chuckling.
Now, if you read that in a tabloid headline, it sounds like he’s declaring war. But the context matters. He was laughing. He told the guy to be careful not to slip on the ice. Most people who were actually there—or at least watched the video—realized he was telling the reporter he was done talking to him, not necessarily making a statement about his lifelong relationship with Luke.
Why the rumors started in the first place
It’s not like these rumors came out of thin air. Luke Grimes, who plays Kayce Dutton, did a pretty deep-dive interview with Esquire and Men’s Health where he was remarkably candid. He didn't bash Costner—far from it—but he did say that filming the final season without him was actually "the easiest season we’ve filmed."
That sounds harsh, right? Well, Luke explained that with Kevin gone, "some of the conflict was gone." He wasn't pointing fingers at Costner specifically, but the massive behind-the-scenes tension between Costner and creator Taylor Sheridan had clearly been a dark cloud over the set for years. When that cloud lifted, the cast could just... work.
Grimes also mentioned that he has Costner’s phone number but doesn't feel like it’s his "place" to reach out. "He’s a big deal," Grimes said. "He can reach out to me if he wants to."
The Reality of the "Feud"
If you look at the facts, there is no evidence of a personal blowout between these two men. In fact, Grimes has been nothing but respectful, calling Costner an "icon" and saying the cast was lucky to have him for as long as they did.
The "conflict" everyone keeps talking about was almost entirely a business dispute.
- Scheduling: Costner was obsessed with his passion project, Horizon: An American Saga.
- Money: Negotiations for the second half of Season 5 reportedly turned sour.
- Creative Control: There were whispers that Costner wanted veto power over scripts, which Taylor Sheridan—a man not known for sharing the pen—was never going to give.
When you spend five years working 12-hour days in the Montana wilderness with someone, you either become family or you become very tired of each other. Or both.
Life after John Dutton
Costner has made it clear he hasn't even watched the Yellowstone finale. He found out about John Dutton’s fate—a gunshot wound in a bathroom—through the media just like everyone else. He wasn't exactly thrilled about the "suicide" angle, noting that it didn't feel like his character, but he’s also not losing sleep over it.
"I'm not even thinking about that," he told Variety. "I don't think I've given it any thoughts. We'll just let it go."
It’s a clean break. For a guy who just spent millions of his own dollars to make a four-part Western epic, a TV show he finished two years ago is ancient history.

What most fans get wrong about the cast dynamic
People want there to be a villain. They want to believe that the cast is divided into "Team Kevin" and "Team Taylor." But talking to the actors reveals a much more mundane reality.
Luke Grimes compared the experience of Costner leaving to the death of his own father—not because of the person, but because of the suddenness. It was a "hump to get over." They had a job to finish. They had to land the plane without their pilot.
The idea that Costner "dismisses" the rumors is less about a formal statement and more about his general aura of indifference. He’s moved on to the next ranch.
What happens next for the Yellowstone family?
While the main series has wrapped up its primary arc, the universe is far from dead. We have 1923 returning, and more spin-offs like The Madison on the horizon.
As for Costner and Grimes? They’re likely just two former colleagues who haven't texted in a while. It happens in every office, even the ones with horses and cowboy hats.
If you're looking for more than a "no comment" from either side, you're probably going to be waiting a long time. Costner is busy with Horizon, and Grimes is leaning into his music career and looking for the "open road" of his next acting gig.
Next steps for fans:
- Check out Costner's Horizon: An American Saga if you want to see what he sacrificed Yellowstone for.
- Keep an eye on Luke Grimes’ music releases; he’s been touring heavily and leaning into that country-rock sound.
- Ignore the TikTok "leaks" about a secret return—John Dutton is gone, and the actors are clearly okay with that.
