Kevin Costner Gets Support From 5 of His Kids at 'Horizon: An American Saga' Premiere

Kevin Costner's kids are his biggest fans!

On Monday night, the actor, 69, attended the premiere for his new film, Horizon: An American Saga, in Los Angeles, and was joined by five of his seven children, who showed up to support their dad's passion project -- a four-part cinematic that is three decades in the making.

Accompanying him to the premiere were sons Joe, 36, Cayden, 17, and Hayes, 15 -- who makes his acting debut in the movie. And of his four daughters, Costner was pictured with his eldest child, Annie, 40, and his youngest child, Grace, 14. The legendary actor is also dad to Lily, 37, and Liam, 26, who did not make it to the event. The movie star's eldest three children come from his relationship with ex-wife Cindy Silva, while he shares Liam with former partner Bridget Rooney. Meanwhile, he shares Hayes, Cayden and Grace with recent ex-wife Christine Baumgartner. The two finalized their divorce earlier this year after 18 years of marriage.

The Costners made Monday's premiere a family affair as they were pictured smiling and posing together on the carpet before heading in to watch Chapter 1 of the Field of Dreams star's four-part saga. Costner opted to wear a tan ensemble, while Hayes and Cayden sported black suits and Joe went with a classic navy blue look. Grace wore a long yellow gown, while her older sister, Annie, sported a multi-colored flowing dress.

The appearance comes after Costner was supported by his children while premiering Horizonat Cannes Film Festival in May. There, the actor smiled while posing with Annie, Lily, Cayden, Hayes and Grace on the carpet. It was a rare appearance for the typically private brood.

It was the best time for his kids to witness their father's magnum opus as he and the entire team received an 11-minute standing ovation upon the ending of the film. Costner later said during a podcast appearance that it was a difficult moment for him as a father and filmmaker.

"I got emotional and my children were there," he shared. "I had five of my children, two of my boys were in tuxes and my three little girls were there all dressed up and they were watching too. And they got a little startled by it, my son had not ever seen me be that emotional."
