Costner’s eldest was born in 1984 and his youngest in 2010, a twenty-six-year spread that trips up almost every page trying to list them

Kevin Costner’s 7 Kids: Names, Ages and Their Three Mothers

The count has been stable for sixteen years. Costner’s four sons are Joe, Liam, Cayden and Hayes; his three daughters are Annie, Lily and Grace. Birth order runs Annie (1984), Lily (1986), Joe (1988), Liam (1996), Cayden (2007), Hayes (2009) and Grace (2010), which is why the family reads as two clear generations with an eleven-year gap in the middle. Six of the seven have birth dates fixed to the day in published family reporting; the seventh, Liam, is dated to the month.

The thing that goes stale on almost every page about this family is the age line. Costner has been written about continuously since 1990, so a huge number of guides quote ages that were captured in 2023 or 2024 and never re-cut. A page that calls Annie 40 and Grace 14 is not lying, it is simply frozen: those numbers were accurate roughly two years ago. The durable facts are the birth dates, which is what this guide leads with, and the ages are shown as arithmetic against a stated day.

Two of the seven are still under 18. For Hayes and Grace this guide records only what their parents put into the public record themselves: name, birth order, parentage, verified birth date, dated age, and a proportionate public milestone where one genuinely exists. No school, no routine, no home detail, no medical history, no social account, and no career invented out of a single red carpet. The five adults get a fuller treatment because their own credited work supports it.

Kevin Costner’s children at a glance

Read the age column as a calculation, not a label. Lily turned 40 on 4 August 2026, sixteen days before this check, so a guide published in July 2026 that called her 39 was correct on the day it was written. Grace turns 17 on 2 June 2027 and stays 16 until then. Cayden crossed into adulthood on 6 May 2025, which is the single most important change to this family page in the past two years: the household that was once described as three young children is now one adult and two teenagers.

The eleven-year gap between Liam and Cayden is what makes the seven feel like two families rather than one. The three eldest were born inside a marriage that ended in 1994; the three youngest were born inside a marriage that ended in 2024. Big blended households like this reward a table over a paragraph, which is exactly how KidsCo handles Robert De Niro’s seven children across four relationships and Steven Spielberg’s seven children including his stepdaughter. A wide spread of ages inside one household is not unusual at this size. Madonna’s six children run sixteen years from the eldest to the twins, and arrived by four separate routes. Pierce Brosnan’s five children split the same way across two branches, two of them adopted after their mother died.

Who are the mothers of Kevin Costner’s seven children?

Three women, three distinct branches, and no overlap between them. Costner married Cindy Silva in 1978 and they divorced in 1994, a sixteen-year marriage that produced Annie, Lily and Joe. Liam arrived in November 1996 from a relationship with Bridget Rooney, a member of the family long associated with the Pittsburgh Steelers. Costner married the designer Christine Baumgartner on 25 September 2004, and Cayden, Hayes and Grace followed in 2007, 2009 and 2010. Branch counting works at smaller sizes too: Kate Hudson’s three children have three different fathers, so one household carries three surnames and no branch overlaps either.

Baumgartner filed her divorce petition on 1 May 2023. The judgment ran through a Santa Barbara County court and the marriage was legally terminated in February 2024 after almost nineteen years. Sources split on the exact day: contemporaneous reporting from the court record gives Friday 16 February 2024 as the date the marriage ended, while some reference summaries carry 20 February, the Tuesday the paperwork was filed and reported. The 16 February reading is the stronger one because it describes the legal effect rather than the day the press saw the document. A heavily reported split leaves the same debris on other pages as it does for Kim Kardashian and Ye’s four children, where a filing, a legal-single ruling and a settlement fall on three separate dates that most profiles flatten into one.

Christine Baumgartner married the financier Josh Connor on 18 October 2025 at a private Santa Barbara County vineyard, roughly twenty months after the divorce concluded. That detail matters for a family guide because it retires the present-tense wording still sitting on a lot of pages, where she appears as an estranged wife or a girlfriend of a family friend. She is Costner’s former wife and the mother of his three youngest children, and she is remarried.

Annie, Lily and Joe: what the three eldest Costner children do

All three of Silva’s children worked on camera as kids, and all three then moved somewhere quieter. Annie appeared in Dances With Wolves in 1990 as Christine, then in The Baby-Sitters Club in 1995 and The Postman in 1997. She stopped acting and moved behind the camera into documentary production, co-founding the company Sound Off Films in 2014 with the producer Adrienne Hall. Her credit list since then is non-fiction: environmental and social documentaries, plus branded documentary work. She married the physician Danny Cox in July 2016.

Lily was born in Los Angeles on 4 August 1986 and shares the same childhood credits, The Baby-Sitters Club and The Postman. Her adult work is music rather than film. She sang a duet, “Heaven’s Gate”, with her father’s band Kevin Costner & Modern West on the 2020 album Tales from Yellowstone, and recorded a version of “Silent Night” with Trace Adkins for his 2013 Christmas record. Her father described her in a 2014 interview as a gifted singer who did not appear to want the scale of fame that would come with pushing harder, and nothing in the record since suggests she changed her mind.

Joe, born 31 January 1988, was in Tin Cup in 1996 and The Postman in 1997 as a child, and he now works in the sound department. His credited roles are technical rather than performing: sound mixing and recording on documentary shorts and series work. That is a genuine professional record with named credits attached, and it is also a good example of why a famous surname does not make a career obvious. Joe’s job is the one on his credit list, not the one a headline assumes.

The three eldest are the reason this family is often mis-summarised. Because all three appeared in their father’s films before they were fifteen, plenty of pages describe them as actors in the present tense. The accurate wording is that each has childhood acting credits and an adult career in a different lane: documentary producing, music, and production sound. The pattern of screen children who chose the crew side is one KidsCo also traces in Michael Douglas’s three children across two marriages.

Liam Costner and the quietest branch of the family

Liam is Costner’s fourth child and the only child of his relationship with Bridget Rooney. He was born in November 1996, which makes him 29 on 20 August 2026 and 30 in November. The exact day of his birth is not fixed by the sources used for this guide, so this page publishes the month, which is the durable part, rather than borrowing a specific date from a profile database that cannot show its working.

What is established is the shape of his life rather than its detail: he has never taken a public-facing role, has no credited professional work in the reviewed record, and has not sought press attention in three decades. Liam is Costner’s son on precisely the terms Annie and Hayes are. The way to show that on a page is a short section that is entirely true, not a long one topped up with filler until all seven entries run to the same depth.

Readers usually arrive at this question from one of two directions. Some are counting: they have seen “six children” on a page that quietly forgot the middle branch, and want to know where the seventh came from. Others have seen Liam’s name in a list of Costner’s children and want to know why there is nothing behind it. The answer to both is the same, and it is a good one: the branch is real, it is documented, and the person in it has stayed private. KidsCo takes the same line with the private siblings in Ewan McGregor’s five children across two branches.

Cayden, Hayes and Grace: the three youngest

Cayden Wyatt Costner was born on 6 May 2007 and is 19. His father has said publicly that he had been wary of having more children in his fifties before Cayden arrived, and then changed his mind. Cayden finished school in June 2025, a milestone both parents attended separately, and he filmed a small appearance in Horizon: An American Saga, Chapter 2, which his father described in a June 2024 interview. Because that film has still not been released, no public cast listing carries the credit yet.

Hayes Logan Costner was born on 12 February 2009 and is 17. He has one credited screen role: Nathaniel Kittredge in Horizon: An American Saga, Chapter 1, released in June 2024, and he spoke about it himself in a dated on-camera interview the same month, saying his father “trapped me” into it and that he had a blast. His father framed it as a way to keep his son near him during a long shoot rather than the start of a career, adding that it might be the boy’s only go at it. That is the correct ceiling for the claim.

Grace Avery Costner was born on 2 June 2010 and is 16. She has been photographed at her father’s film premieres, including the Los Angeles premiere of Horizon: An American Saga, Chapter 1 on 24 June 2024, where five of the seven children appeared with him. Being photographed at a premiere establishes that she was photographed at a premiere. It does not establish a job, a school, a home, an interest or a personality, and the anecdotes about her hobbies that circulate elsewhere come from her father’s talk-show chat when she was five years old. Guides that keep recycling them are describing a small child who is now a teenager.

The privacy line here is the same one KidsCo applies to Nicole Kidman’s four children across two branches: minors get names, dates, parentage and the milestones their parents chose to make public, and nothing that would follow them into adulthood.

Which Costner children have actually appeared on screen?

Six of the seven have some form of screen record, but the records are not equivalent, and the difference between a credit and a photograph is where most family pages fall over. The table below separates them.

The Hayes entry is the one worth reading twice. A credited role in a released feature is a real, checkable professional record, and it is right to name the character and the film. It is also a single job taken at 15 with his father directing, which his father openly described as a way of keeping him close. Calling that “an acting career” inflates one credit into a life, and calling it nothing at all pretends a credited performance did not happen. The accurate version sits between the two, and it fits in one sentence.

Kevin Costner is a grandfather, and what he is doing in 2026

Almost no page built around the phrase “Kevin Costner’s 7 kids” mentions that the family already runs to a third generation. Costner confirmed it himself on American television around Father’s Day 2024, describing what he enjoys about being a grandparent as watching how his own children parent. He returned to it in a June 2025 interview, saying that gathering all seven at once has become difficult as they move in different directions, and that he designs his homes so his children and their children want to come back.

Annie is the child publicly identified as a parent. The names and birth dates of the grandchildren are not established by strong, dated sources, and they are children of private adults, so this guide states the generation without naming them. That is not a gap in the answer, it is the answer: the reader can now say with confidence that Costner is a grandfather, that the confirmation came from him, and that the detail below it belongs to the families involved rather than to a search result.

His own working record has moved as well, and it changes how the family page should read. He confirmed in June 2024 that he would not return to Yellowstone, ending a run that began in 2018. Horizon: An American Saga, Chapter 1 reached cinemas in June 2024 and took roughly 38.7 million dollars worldwide against a 50 million dollar budget. Chapter 2 premiered at the Venice Film Festival in September 2024, was pulled from its planned theatrical date, and as of April 2026 reporting still had no release. In between, he hosted the eight-part History Channel series Kevin Costner’s The West, which premiered on 26 May 2025.

What most Kevin Costner family pages still get wrong

The seven-child count is the easy part and almost everyone gets it right. The errors cluster in the four lines underneath it: the ages, the tense, the jobs and the money. Here is what a reader should fix on sight.

There is one more that is easy to miss. Several pages describe Hayes as appearing in “the Horizon films”, plural. One chapter is released and carries his credit; the second is finished and unreleased, and the appearance in it belongs to his older brother Cayden. Getting that right takes eight words and saves a reader from looking for a credit that has not been published.
