The Yellowstone hunk, 69, was pictured making his way to the restaurant with his youngest daughter Grace, 13. Kevin’s sons Cayden, 16, and Hayes, 15, arrived separately to join their A-List father.
Afterwards, Kevin — who recently revealed he would ‘love’ the opportunity to return to his role as John Dutton for the final season of Yellowstone — and Grace stopped off at clothing store K. Frank for some retail therapy.
Kevin shares his three youngest children with ex-wife Christine Baumgartner, 50. The pair finalized their bitter divorce in February, 2024.
The day before Christine and her new boyfriend Josh Connor, 49, were spotted out together after enjoying lunch and some shopping in Calabasas.
For his Sunday outing Costner looked sharp in a black sweater, khaki pants, and grey sneakers.
The busy actor shielded his eyes with a pair of black sunglasses and held a cellphone in his hand.
Meanwhile Grace showed off her youthful style in a blue hoodie and brown UGG slippers.
Like their sister the boys also opted for casual ensembles as they joined the family lunch.
Costner also shares Annie, 40, Lily, 37, and Joe, 36, with his first wife, Cindy Silva, 67. The pair were married from 1978 until 1994. He is also father to Liam, approximately 28 years old, whom he shares with former partner Bridget Rooney.
Earlier this year, DailyMail.com exclusively revealed Baumgartner had moved on with Costner’s banker buddy Connor – just four months after her bitter divorce from the star.
During her Calabasas outing with Josh, Christine was all smiles as she donned a trendy look consisting of a white t-shirt and dark 90s style jeans.
She added a touched of luxury with a gold jewelry and a purse which she carried over her shoulder.
Her blonde locks cascaded over her shoulders and bounced in the wind while she wore light makeup.
Connor cut a casual figure as he wore a black t-shirt and joggers paired with some trendy sneakers and sunglasses.
Since getting together, the couple moved fast.
They traveled together at Christmastime – her new banker beau flew her to Hawaii on a private jet, sources told DailyMail.com.
Connor, himself a divorced father of three, became legally single on January 3, 2023 – just five months before Baumgartner blindsided Costner by filing for divorce.
The financier is a managing director and co-portfolio manager of Oaktree Capital’s Infrastructure Investing strategy, specializing in the transportation sector.
Earlier this year, both Christine and ex Kevin settled their divorce after she filed last year in May following 18 years of marriage.
While the specific settlement details are undisclosed, TMZ reported that the couple’s prenup was upheld by the judge.
Both ex-spouses pursued joint custody, and Christine is granted $63,209 monthly in child support. The settlement was signed by Costner, Baumgartner, and their lawyers Laura Wasser and Marisa Beuoy.
They decided to forgo co-parenting classes, typically mandatory in such cases.
However, it has since been reported that Costner had suspected that ‘something was going on between Christine and Josh,’ a source informed Us Weekly.
The insider also added that the new couple’s ‘close [bond] was a real elephant in the room.’
The source also told the publication that since the Oscar winner has also moved on, ‘Christine doesn’t think Kevin has anything to complain about.’
‘Josh has been Christine’s rock throughout the divorce ordeal. If Kevin has a problem with that, that’s on him,’ and also noted that the couple’s close friendship had turned romantic ‘relatively recently.’
In December, Costner was romantically linked to singer Jewel, with a source telling People, ‘The relationship between Kevin and Jewel is fresh but not brand new. There is very big attraction on both sides.’
‘Jewel likes Kevin’s type and Kevin likes to be in a relationship, so this is cool,’ the insider continued. ‘He is having fun after his contentious divorce. He is glad that is over.’
