Kevin Costner made a subtle new dig after being questioned about his ex-wife Christine Baumgartner’s current relationship with their former neighbour Josh Connor.

During an interview with paparazzi, the actor was asked about his feelings on his ex-wife dating their neighbour.

“I don’t have a next-door neighbor,” he replied in a video acquired by Entertainment Tonight.

His angry remark comes a month after rumors surfaced that Baumgartner took her affair to the next level by moving in with Connor after their divorce was finalized.

An insider had previously told Us Weekly that the Yellowstone star had “strong suspicions that something was going on between” them.

However, Baumgartner ignored her ex-husband’s concerns, claiming that the actor had been linked to Jewel since December 2023 and so had “anything to complain about.”

The insider went on to say that the new pair has been doing well in the aftermath of her divorce, so Costner’s judgement of their new relationship is immaterial.

“Josh has been Christine’s rock throughout the divorce ordeal,” the source explained.

“If Kevin has a problem with that, that’s on him.”

Meanwhile, Costner’s affair with Jewel is progressing well, with a source stating that ‘they tick a lot of boxes for each other’.

“Kevin and Jewel had an extremely high opinion of each other and have always gotten along great,” a source said.
