Mila Kunis and Josh O’Connor Had ‘Real Chemistry’ While Promoting ‘Wake Up Dead Man’

Costars Mila Kunis and Josh O’Connor got on like a house on fire filming 2025’s Wake Up Dead Man together and they’re still in frequent contact, says a source who spills their bond is testing the patience of her hubby, Ashton Kutcher.

Mila, 42, plays a detective while Josh, 35, is a priest in the Netflix mystery film, and although she’s wed to Tinseltown heartthrob Ashton, 48, dad of her daughter Wyatt, 11, and son Dimitri, 9, a source notes that she has a fondness for “quirky” guys like her ex-boyfriend Macaulay Culkin.

“Mila was with Macaulay for years, and she has a taste for the quirky and off-center kind of guy,” says the source. “Working with Josh got to her. You see it whenever they’re in the same room and during the entire press tour. They have real chemistry, the kind you can’t fake. The real question is, how will Ashton handle their ongoing closeness? Even on a good day, he can be a real jerk.”

While Mila and Ashton, who first became pals starring on That ’70s Show from 1998 to 2006, have been married since 2015, Josh is dating Wuthering Heights beauty Alison Oliver, 28, who he reportedly met at her sister’s September 2024 wedding.

Still, sources say Mila’s friendship with Josh has Ashton’s nose out of joint.

“Ashton needs to be realistic. Of course, you’re going to make new friends and hit it off with new costars. Josh is a safe guy for Mila to flirt with because he is in an extremely serious long-term relationship,” the source dishes. “And Josh is on his best behavior because he desperately wants to be the next James Bond.”
