Yellowstone follows the formidable Dutton family at their powerful Montana cattle ranch. Hollywood icon Kevin Costner stars as John Dutton, the patriarch of the Yellowstone Dutton Ranch.
John Dutton will stop at nothing to protect his land and family. Along with his children, Beth, Jamie, and Kayce, John works tirelessly to prevent expanding neighboring borders from threatening his ranch.
Many viewers of the show have become curious if Kelly Reilly, who plays Beth Dutton, is the daughter of Kevin Costner in real-life.
On-screen, the actors have great chemistry, appearing that they could actually be father-daughter in real life.
Is Kevin Costner’s Daughter in Yellowstone?
No, Kevin Costner’s daughter is not in Yellowstone. The actress who plays Beth Dutton, Kelly Reilly, is not related to Kevin Costner.
Though they play on-screen father and daughter, they are not related to each other in any way.
Costner is the father of seven children: Annie, Lily, Joe, Liam, Cayden, Hayes, and Grace. While Annie, Lily, and Joe have all acted before, none of them appeared in Yellowstone alongside their father.

Kevin Costner’s daughter Annie appeared alongside him in Dances With Wolves and The Postman. Her other credits include The Baby-Sitters Club and Lazy Teenage Superheroes.
Lily Costner also appeared alongside The Postman with her father. She also appeared in The Baby-Sitters Club as well.

Costner had his children Annie, Lily, and Joe with his first wife Cindy Silva. He had his son Liam with Bridget Rooney, whom he had a brief relationship with. Costner had his three youngest children, Cayden, Hayes, and Grace, with his second wife Christine Baumgartner.
“I work as a provider. I’m a father and I’m a husband, but the world doesn’t revolve around me. When I’m not making a movie, I’m living and on the freeway with my wife, getting the kids to their stuff or I’m waiting for them to come out of a party. I’m just twiddling my thumbs. People have a wrong idea about how my life works,” said Costner about his family.
Does Kelly Reilly Have Children?
Kelly Reilly has never mentioned having children. Reilly remains private about her personal life, not sharing many details outside of her career.
