Kevin Costner’s estranged wife steps out with daughter Grace amid divorce

Kevin Costner’s estranged wife is focusing on her children amid her divorce from the “Yellowstone” star.

Christine Baumgartner was spotted purchasing balloons in Montecito, Calif., over the weekend for her son Cayden’s 16th birthday.

Baumgartner brought along her 12-year-old daughter, Grace, for the errand.

The model looked chic in a pair of white cropped jeans and an animal-printed top, while her daughter kept it casual in an oversized hoodie and baggy jeans.

Notably, Baumgartner‘s wedding ring was nowhere to be found.

Baumgartner, 49, filed for divorce from the “Field of Dreams” star last week after 18 years of marriage.

She cited irreconcilable differences as the cause of the split.

“It is with great sadness that circumstances beyond his control have transpired which have resulted in Mr. Costner having to participate in a dissolution of marriage action,” a rep for the “Bodyguard” actor said in a statement.

“We ask that his, Christine’s, and their children’s privacy be respected as they navigate this difficult time.”

Sources told Page Six exclusively that Costner, 68, was left “stunned” by Baumgartner’s filing — but adamantly denied that infidelity played any role in the split.

“There was no issue of cheating at all,” a longtime friend of Costner’s told us.

Costner and Baumgartner attended the 2023 Oscars together in March and appeared happy when posing for photos together, prompting his pal to tell us: “Kevin was very surprised by Christine’s actions, he obviously doesn’t want the divorce and he would take her back.

“It’s disappointing, he loves her and he loves his children.”

In addition to Cayden and Grace, the couple also share 14-year-old son Hayes. Costner also has three other kids from his first marriage to Cindy Silva, as well as a son with ex Bridget Rooney.

The “Dances With Wolves” star responded to his estranged wife’s filing and requested joint custody of their kids. Famed divorce attorney Laura Wasser is representing Costner through the dissolution.
