There are NEW reports of trouble on the set of "Yellowstone" . . . and if you're a fan, you won't want to hear them.
So-called "sources" are saying that the show will END after the second half of Season 5 . . . because Kevin Costner just can't get along with the show's creator, Taylor Sheridan.
But it sounds like it's not Kevin's fault. A so-called "insider" says, quote, "Taylor is the star of his show. He's the most important person on all of his shows."
The first half of Season 5 ended in January. There's no word when the second half will air . . . or even when it'll start filming.
