Kevin Costner has broken his silence on the shock Yellowstone finale and his rumored feud with former co-star Luke Grimes. Costner, who left the show amid a rift with showrunner Taylor Sheridan, stepped out in Aspen just days after the finale aired, and weeks after his character John Dutton was killed off in a faked suicide. In a video from someone in Aspen, Costner said: “I'm not thinking about [the Yellowstone finale], I don't think I've given it any thoughts, we'll just let it go.” He also shut down a question about his alleged feud with onscreen son and Kayce Dutton actor Grimes, and revealed he hadn't been in contact with him since the finale aired. Last week, Luke revealed that filming without Costner made things much smoother for him and the rest of the cast.
