Kevin Costner has 7 kids, including 3 with estranged wife Christine Baumgartner, who is seeking $248K in monthly child support. Here's everything you need to know about them.

• Kevin Costner and Christine Baumgartner, who are divorcing, share three teenage children together.

• The "Yellowstone" star also has three adult children with his first wife Cindy Silva.

• Between his marriages, Costner also fathered a son with former partner Bridget Rooney.

Kevin Costner plays one of television's most recognizable father figures on "Yellowstone," and in real life, the actor has a large brood too.

The award-winning actor, 68, shares three adult children — Annie, 39, Lily, 36, and Joe, 35 — with his ex-wife Cindy Silva, as well as son Liam, 26, with his former partner Bridget Rooney.

With his estranged second wife Christine Baumgartner, he welcomed sons Cayden, 16, and Hayes, 14, and daughter Grace, 13. The former couple, who wed in 2004, are now locked in an increasingly contentious divorce.

According to court documents filed on Baumgartner's behalf that Insider has viewed, the soon-to-be former Mrs. Costner has requested that the actor pay her $248,000 a month in child support for their three children.

In her filing, Baumgartner explained that the family lived a jet-set lifestyle that included private planes, multiple sprawling estates, lavish vacations to the Caribbean and Hawaii, memberships to country clubs, private chefs, and elite schools for their children.

She also wants the "Yellowstone" actor to pay for the kids' private-school tuition, extracurricular activities, and sports as well as their healthcare expenses.

Annie Costner, 39

Annie Costner was born on April 15, 1984, and is the "Bodyguard" actor's eldest child with his first wife, Cindy Silva.

Kevin and Silva, met when they were both students at California State University in the mid-70s and married shortly after they graduated in 1978 before splitting in 1994.

As a child, Annie appeared in her father's movies "Dances With Wolves," "Waterworld," and "The Postman," often in uncredited or minor roles. She also appeared in "The Baby-Sitters Club," where she played a character with her own name.

She has moved into producing and has been working for Sound Off, a production company she cofounded in 2014, which is focused on documentary and non-fiction storytelling.

Through the company, Annie has produced various documentaries, including Katy Perry's "Witness: The Tour."

In 2014, Kevin told the Huffington Post that in addition to her documentary work, Annie also "helps write legislation in Rhode Island" on environmental issues.

Lily Costner, 36

Kevin and Silva's second child together, Lily Costner, was born two years after her older sister on August 4, 1986, per People.

Like Annie, she appeared in "The Baby-Sitters Club" and "The Postman."

As an adult, she has pursued a career in music and has been credited on the soundtrack of two of her father's films: "Black or White" and "3000 Miles to Graceland."

She also collaborated with her father's band, Kevin Costner and the Modern West, on the song "Heaven's Gate" from the 2020 album "Tales of Yellowstone," inspired by the actor's television alter ego.

Kevin described Lily as an "amazing singer and songwriter" to Huffington Post and said while she could "be a really huge star" he's "not sure she wants that."

Joe Costner, 35

Joe, who is Kevin and Silva's youngest child together and only son, was born on January 31, 1988.

Like his sisters, he had small acting parts in his father's films when he was a youngster, and is the only one of the three to appear in his dad's 1996 golfing movie, "Tin Cup."

It seems that musical talent must run in the family as Joe now works as an audio engineer and production sound mixer, according to his LinkedIn page.

He previously worked as a sound mixer for his older sister Annie's production company but has since founded his own company, Spartan Recording, according to Good Housekeeping.

Liam Costner, 26

Kevin and girlfriend Bridget Rooney welcomed son Liam Costner on November 15, 1996, two years after his divorce from Silva was finalized, according to Good Housekeeping.

However, Kevin's relationship with Rooney, the niece of the late Pittsburgh Steelers owner Dan Rooney, didn't last very long.

In 2005, when Liam was 9 years old, his mother remarried to billionaire William Koch.

Not much is known about Liam as he largely stays out of the spotlight.

Cayden Costner, 16

Cayden Wyatt Costner was born on May 6, 2007, three years after Kevin and Baumgartner married in 2004. He is the eldest of the three children the couple share.

When he was born, Kevin was 52 and expressed worries about being an older dad. Kevin's hesitation about becoming a dad again was one of the reasons the couple briefly separated in 2002 before reuniting.

"I hope I have as much energy for Cayden as I had for my first," the actor told People, adding that he had fears that "someone [else] will raise him, meaning that my life will end prematurely."

Kevin told Huffington Post that Cayden is "so full of life and adventure" and likes to hear "stories of adventure that I've done" rather than regular bedtime stories. He added that he was "a good older brother" to his siblings.

Hayes Costner, 14

Kevin and Baumgartner's second child together, Hayes Logan Costner, was born on February 12, 2009.

According to People, Kevin chose the moniker as it's "a great Western name" and he planned to also use it in a Western film that he was working on.

In a 2016 interview with "Today," the "Field of Dreams" star said that Hayes was showing a talent for sports and playing little-league baseball with 8 and 9-year-old kids, saying "He's 6 and he can hack it."

Last year, Kevin told People that Hayes has a small part in his upcoming four-movie Western saga, "Horizon."

"He's very good," he said. "But I kind of did it on purpose, so he could be hanging out with me."

Grace Costner, 13

Grace Avery Costner was born on June 2, 2010, and is the youngest of Kevin and Baumgartner's three children. She is also Kevin's youngest child overall.

Kevin has described her as his "girly girl."

Speaking on "Today", he said, "She's sewing and dancing, but when she sees the ball bouncing out in the backyard, I can feel her gravitate out with the boys."
