Joe Costner is the youngest child of Kevin and Cindy Costner. He has also had acting experience and starred alongside his sister, Lily in “The Postman.”
He had a role in his dad’s film “Tin Cup,” but Joe doesn’t seem to be active as an actor anymore. These days, he seems to prefer the quiet life as the son of a notable movie star.
Though his youngest children are with Christine Baumgartner, Costner also has 3 much older children. His oldest, from his marriage to Cindy Costner, is Annie Costner. She appeared in three of his films including "Dances with Wolves," "Waterworld," and "The Postman."
Annie graduated from Brown University in 2006 and now works as a producer in Hollywood. In 2016, she walked down the aisle, escorted by her dad, to marry California native, Dr. Danny Cox.
Lily Costner is the second-born daughter of Kevin and Cindy Costner and has also acted a few times in different projects such as "The Babysitter Club." In 2004, she was chosen as Miss Golden Globe (a title known today as Golden Globe Ambassador).
Her real passion though appears to be music. She has performed in her dad’s band, Dances with Wolves, and has also collaborated with singers like Trace Adkins.
Liam Costner, Kevin’s son with ex-girlfriend Bridget Rooney, Is the fourth child of the actor. A trust fund was set up for Liam but little is known about the twenty-something.
He, like his other siblings, seems to enjoy a quieter life. But with an actor for a father and a former model as a mother, it’s possible he may step into the spotlight someday.
