Paramount Network drama series Yellowstone follows the fortunes of the Dutton family. The Yellowstone ranch is owned by John Dutton (played by Kevin Costner) and his children Beth (Kelly Reilly), Kayce (Luke Grimes) and Jamie (Wes Bentley). But some audience members have been wondering whether Reilly is the daughter of Costner off-screen as well as on the show.
Although they play father and daughter in the show, Reilly and Costner are not related in reality.
Double Oscar winner Costner has seven children in total but Reilly is not one of them.
Costner has three children from his first marriage to college sweetheart Cindy Silva.
They were married for 16 years between 1978 and 1994 before calling time on their relationship.
