Although it may not be readily apparent, Lilli Kay had some pull when she was cast in Season 5. When she first caught "Yellowstone" fever, it was because her father directed episodes for the series. Stephen Kay has worked on the series for several years, and after hearing about tales from the set, Kay wanted to be a part of it. She also has the bonus of working beside her stepmother, Piper Perabo. "Yellowstone" became a family affair, and Kay couldn't be happier.

"My dad directs a lot of the show and EPs the show, which was a very sneaky move that I made," Kay confessed to Deadline. "I've not been able to do jobs with my dad. It was literally a dream come true. The number of days that I came home from work crying over how amazing it was to hang out with both dad and Piper at work ... I was like, 'oh my God, this is my dream.'" Kay may love working with her family, but it can also have drawbacks. Romance seemed to be in the air on the day Stephen Kay was directing the famous fair scene in Season 5 of "Yellowstone." Not only did he have to direct a romantic scene with his daughter in the background, but his real-life wife, who kissed Kevin Costner in the same scene. Family, it seems, can be a double-edged sword.
