Kevin Costner’s 18-year marriage to Christine Baumgartner ended in a divorce that shattered the Hollywood fairy tale their union had long appeared to be. Behind the red carpets and public displays of devotion, the couple’s relationship had been quietly strained for years by the demands of Costner’s career, prolonged separations, and financial pressures stemming from his ambitious passion projects. The breakup, which became official in May 2023, exposed a bitter legal war over child support, housing, and the terms of a strict prenuptial agreement—all playing out in public view. Costner, 69, and Baumgartner, 50, first crossed paths in the mid-1990s on a golf course while Costner was preparing for the film Tin Cup.
Their connection remained casual until they reunited at a restaurant in 1998, when Costner asked for her phone number—but requested he wait exactly two weeks before calling, a move he later admitted was a social misstep. They began dating shortly after, though the relationship hit a serious roadblock in 2002 when Baumgartner, then in her late 20s, wanted children of her own. Costner, already a father of four from previous relationships, was hesitant to start a new family and admitted fear kept him from committing. After months of reflection, he realized he was risking losing true love over that fear, and the couple reunited before the end of that year.
Costner proposed in 2003, and they married on September 25, 2004, at his private 160-acre estate Dunbar Ranch near Aspen, Colorado. The ceremony featured Costner arriving by horse-drawn carriage and Baumgartner in a vintage green pickup truck, with roughly 300 guests present. They welcomed three children together: sons Cayden, born 2007, and Hayes, born 2009, and daughter Grace, born 2010. Bythe time the divorce was filed, the couple was legally separated on April 11, 2023, with Baumgartner submitting a petition for dissolution on May 1, 2023, citing irreconcilable differences in Santa Barbara County Superior Court.
Costner’s representatives issued a statement expressing sadness, noting that circumstances beyond his control had forced him to participate in the divorce action. Baumgartner later alleged that Costner told their three children about the impending split via a brief 10-minute Zoom call broadcast from a Las Vegas hotel room while on location, without her consent or presence. She said she had wanted to wait until he returned home so they could tell the children together in person, but he disregarded her proposal. The divorce battle was defined by a highly restrictive prenuptial agreement signed on September 17, 2004, just days before the wedding.
Costner insisted on the document after his 1994 divorce from his first wife, Cindy Silva, resulted in a historic $80 million settlement. The prenup entitled Baumgartner to a lump sum of roughly $1. 5 million, tax payments, and specified she must vacate all Costner-owned properties within 30 days of any divorce filing. When the deadline expired in June 2023, Baumgartner refused to leave the couple’s primary home, a cliffside compound valued at an estimated $145 million in Carpinteria, California.
She argued she could not safely relocate three teenagers without first establishing a court-mandated monthly child support payment to fund comparable housing. Costner offered $30,000 per month for a rental house and a $10,000 advance for moving costs. On July 5, 2023, Judge Thomas P. Anderle upheld the prenup’s housing clause, ordering her to vacate the main house by July 31, 2023.

The most contentious issue erupted over child support. In June 2023, Baumgartner’s legal team requested $248,000 per month, claiming the total was less than needed to maintain the children in their accustomed lifestyle. Her declaration detailed a hyper-luxurious life of global travel and private amenities, stating a life of luxury was in the teenagers’ DNA. Costner argued the historical baseline cost for the children’s needs was closer to $51,000 per month, offering a compromise of $75,000.
He testified that his biggest concern was being ordered to pay support above the needs of his children and for the needs of his ex-wife, claiming she allocated 60% of expenses—including private trainers, unallocated credit card charges, and her plastic surgery—to the minor children. Costner’s forensic accountants presented evidence alleging Baumgartner had spent $188,500 on personal cosmetic procedures over a short period, while family spending in 2022 totaled an average of $240,000 per month, including large cash withdrawals, boutique shopping, and spa treatments. They also submitted evidence showing she had charged $100,000 to the personal credit cards of Costner’s estate staff to pay her private attorneys before filing for divorce. During cross-examination, Baumgartner admitted receiving a discreet $20,000 cash payment from family neighbor Josh Connor during a Hawaii trip in July 2023, which she maintained was a loan to give cash gifts to her mother.
She denied Connor was her boyfriend at the time. On September 1, 2023, Judge Anderle ruled in Costner’s favor, slashing support to a final order of $63,229 per month—roughly a quarter of what she had initially demanded
The legal war came to an unexpected end on September 19, 2023, when both parties suddenly signed a three-page settlement agreement just before a massive public trial was set to challenge the prenup’s validity. Baumgartner capitulated to avoid a trial that could activate the prenup’s fee-shifting clause, which would have required her to repay Costner more than $1 million and pay his attorney’s fees. The final settlement package was sealed,but documentation showed Costner agreed to pay an enhanced amount slightly above the baseline $1.
5 million allotment. Both sides released a joint statement confirming an amicable resolution and commitment to co-parenting. The final decree specified Costner would pay 100% of the children’s health insurance, private school tuitions, extracurricular activities, elite sports coaching, and their oldest son’s vehicle costs. The $63,000 monthly child support remained in place.
The marriage was officially legally dissolved on Friday, February 16, 2024, when the final judgment was signed. In a unique addition, the court waived the standard mandatory co-parenting education classes, reflecting confidence in both parties’ ability to co-parent without state intervention
After the divorce was finalized, Baumgartner’s relationship with Josh Connor, a wealthy financier and former neighbor, progressed openly. They had been neighbors in Montecito and developed a close friendship that turned romantic after both experienced divorce. On October 20, 2025, she formally married Connor during a small, private, beachside ceremony in Santa Barbara.
Meanwhile, Costner was romantically linked to singer-songwriter Jewel after they were spotted together at a charity tennis event on Richard Branson’s Necker Island in late 2023. He publicly denied any romantic involvement during a 2024 press tour, telling Howard Stern they had never gone out and that he did not want rumors to ruin their friendship. In June 2024, on CBS Mornings, Costner spoke candidly about the emotional toll of the divorce, calling the collapse of his marriage a deeply crushing, powerful, hurtful moment, but emphasizing he had no choice but to move forward for the sake of his kids. He added that his children were looking at him, so he could not wilt like a daisy.
The divorce, though painful, brought a measure of closure: Costner protected his assets and his prenuptial agreement, while Baumgartner secured an enhanced financial package and the freedom to move on with her life
