Luke Grimes Confirms He Hasn’t Spoken to Kevin Costner Since “Yellowstone” Exit
The “Yellowstone” universe continues to evolve, but the connection between two of its central figures appears to have cooled significantly. In a recent interview, Luke Grimes, who portrayed Kayce Dutton, opened up about his current relationship with Kevin Costner, the actor who played his father, John Dutton. Grimes confirmed that the two have not spoken since Costner’s departure from the hit series in 2024, citing busy schedules and the natural progression of life as the reasons behind their distance.
Life Moves On: Grimes Addresses Costner Communication
During a conversation with USA Today, Grimes was direct about the status of his relationship with Costner. “I haven’t talked to Kevin since we stopped working together. Not for any reason other than we’re busy guys and life moves on,” he stated plainly. This comment puts to rest any speculation about lingering tension or unresolved issues between the co-stars, framing their lack of contact as a simple matter of circumstance rather than conflict.

Grimes’ candid remarks come as he promotes his new series, “Marshals,” a Taylor Sheridan spinoff that sees his character Kayce Dutton transition from the ranch to an elite unit of U.S. Marshals in Montana. The shift in setting and role has kept Grimes busy, much like Costner’s focus on his “Horizon: An American Saga” film series has occupied his time.
“Marshals” and the Costner Question
Given the shared “Yellowstone” universe, questions were inevitable about whether Costner might make an appearance on “Marshals.” Grimes acknowledged that a crossover would be “cool” but expressed doubt that it would ever happen. “I doubt that that would ever happen,” he said, though he left the door slightly ajar for a flashback scenario.
Instead of a return for John Dutton, Grimes shared his preference for a more poignant character connection. “If there was a flashback, I would probably rather it be with Monica [Kelsey Asbille] than John. I think that would be more poignant to the character, but we’ll see,” he added, highlighting the emotional weight of Kayce’s relationship with his wife over his father.

The “Yellowstone” Divide: Understanding Costner’s Exit
The rift between the actors mirrors the complex behind-the-scenes dynamics of “Yellowstone” itself. Costner’s exit from the series during season five was the result of a long-running scheduling dispute. The actor prioritized his passion project, the “Horizon” film series, amid production delays and a reported lack of scripts for the second half of the season. Costner disputed claims that he left simply for his films, pointing to the production issues as the primary cause.
The situation was further complicated by comments from series creator Taylor Sheridan. On “The Bill Simmons Podcast,” Sheridan revealed that Costner had originally only agreed to appear for three seasons of “Yellowstone” and was ready to move on. However, he decided to stay once the show became a massive hit, extending his commitment. This history of shifting agreements and high stakes underscores the complicated nature of maintaining a long-running television drama with a star of Costner’s caliber.

A New Chapter for Kayce Dutton
While the John Dutton character’s fate remains a point of discussion, Grimes is fully focused on the new path for Kayce in “Marshals.” The series marks a significant evolution for the character, moving him away from the ranch and into a new world of law enforcement. For Grimes, this represents a fresh chapter, one that stands on its own while honoring the legacy of “Yellowstone.”
The actor’s ability to transition his established character into a new series demonstrates the expansive nature of Taylor Sheridan’s television empire. Despite the real-life distance between its stars, the fictional world of the Dutton family continues to branch out in compelling new directions, leaving fans to wonder what the future holds for this sprawling narrative.

Looking Ahead
The confirmation that Grimes and Costner have not spoken since their professional paths diverged brings a sense of closure to a storyline that has fascinated fans for years. While the door remains technically open for a future cameo, the focus now shifts to Grimes’ new venture and the continued expansion of the “Yellowstone” universe through spinoffs and prequels. The narrative moves forward, much like the lives of the actors who brought it to life.
