Luke Grimes revealed in a recent interview with USA Today that he has not spoken to Kevin Costner since their time together on the television series Yellowstone. Grimes, who now stars in the Western drama’s spin‑off Marshals, said, “I’ve never spoken to Kevin since we stopped working together,” underscoring a complete break in their off‑screen relationship.

The two actors portrayed a father‑son duo on the popular series, which ran for six seasons under the direction of creator Taylor Sheridan. Sheridan’s drama concluded in 2023, after which Grimes transitioned to lead the new show. The comment highlights how on‑screen collaborations can sometimes diverge from real‑life interactions, a phenomenon that has drawn attention from fans and industry observers alike.

While the reasons behind Grimes’s decision to sever contact remain unconfirmed, the statement illustrates the personal dynamics that can surface within long‑running productions. It also raises questions about the professional and personal boundaries that actors navigate when their on‑screen relationships are deeply intertwined with their real‑world interactions.

Looking ahead, Grimes’s focus appears to be on Marshals, where he will continue to build his career in the Western genre. The show’s development and premiere schedule will likely keep the actor in the public eye, while the nature of his relationship with Costner remains unchanged. Fans can expect further updates from the network and Grimes himself as the new series moves forward.
