Kevin Costner and his ex-wife Christine Baumgartner kept things frosty on Friday as they attended their son Cayden’s high school graduation.

The Oscar-winner, 70, and the former handbag designer, 51, finalized their bitter divorce in February 2024 after a highly publicized legal showdown.

Pictures obtained by the Daily Mail showed Costner icing out his ex-partner – who is engaged to his former friend Josh Connor – as they celebrated in Santa Barbara, with their son awkwardly smiling for photos.

Though more than a year has passed since their blockbuster legal battle, the graduation made it clear the rift hasn’t fully healed.

The exes kept their distance, carefully avoiding interaction and sidestepping any direct encounters.

In contrast, the father of seven looked giddy as he happily posed with Cayden, 18, and daughter Lily, 38, who he shares with ex-wife Cindy Silva.

An insider has given a candid insight into the pair’s awkward reunion as they endeavored to ‘put their differences aside.’

At one point, he wrapped his arms around Cayden for a proud photo and also embraced his eldest daughter Lily, 38—whom he shares with ex-wife Cindy Silva—as well as posing with Annie, 41, and Joe, 37, his other children with Silva

The source said: ‘They obviously knew each other were there but neither made any effort to interact with each other. It is pointless. The good days that they had in the past are long gone.’

They added ‘the day was all about Cayden, to celebrate him, to celebrate the achievement of graduating,’ and while ‘the less time that Kevin is around Christine, the better,’ both parents put their differences aside for their son.

‘Stuff like this takes precedence,’ the insider said. ‘So, being in the same place at the same time can be challenging, but at least it was buffered by a wonderful and amazing achievement and moment.

‘Cayden loved that his parents were there to support him, it was a fun day and everyone knows the drill.

‘Kevin loves his kids and made sure that his issues with Christine made no appearance to the festivities.’

As for the former couple’s dynamic, the source noted: ‘From time to time, this is Kevin’s new normal. His interaction with Christine is extremely minimal and this was no different.

‘It is better off that way, nobody wants issues or arguments around special moments like this.

‘Everyone stayed away, got through it and Cayden was happy and Kevin and Christine were happy for Cayden.’

Dressed casually in a pale shirt, white pants, and a light jacket, Costner kept a low profile behind sunglasses during the event.

Costner’s large blended family also includes son Liam, 28, from his relationship with Bridget Rooney.

Kevin and Christine’s other children — Hayes Logan, 16, and Grace Avery, 15 — were also in attendance at the graduation, posing for photos with Cayden.

She appeared relaxed and upbeat, keeping her attention focused on her son and steering clear of her former husband.

At one moment during the ceremony, Kevin was seen watching from the stands alone, before relocating to sit beside Lily, where he greeted her with a warm hug.

Baumgartner filed for divorce from Costner in May 2023 citing irreconcilable differences.

Costner was ultimately ordered to pay $63,209 per month in child support — a far cry from the staggering $248,000 Christine had initially requested.

The animosity also led to Baumgartner being ordered to vacate Costner’s $145 million beachfront estate in Carpinteria just two months after filing for divorce.

Given Kevin and Christine’s contentious history, the frosty reunion comes as little surprise — DailyMail.com recently reported that tension continues to simmer behind the scenes.

As previously revealed by DailyMail.com, Christine is quietly planning a tropical wedding with her fiancé, financier Connor, just 18 months after her split from the Yellowstone star. 

Christine and Josh’s relationship has sparked controversy since the beginning. 

During a heated court hearing in August 2023, Costner accused his ex of cheating on him with Connor—who was once a close friend and neighbor to the couple. 

Christine denied the claims under oath, but by January 2024, their romance had become public knowledge.
