“I’m not getting a ton of marital advice,” Stiles, 36, told PEOPLE in 2016. “We’re really slow on the wedding planning so I haven’t really been soliciting advice. Somebody told me about radical empathy, but I’m still trying to figure out what that means. I’m trying to figure out what makes it radical.”
The couple met on the set of 2015’s Go with Me, where Cook worked as a camera assistant.
Stiles is currently in London promoting her new series, Riviera, an upcoming 10-part thriller series coming to the U.K.’s Sky Atlantic.
Stiles plays Georgiana, a woman recently married to Constantine Clios, a billionaire killed in a yacht explosion in the South of France. Upon his death, Georgiana discovers their lavish lifestyle was made possible by criminal behavior, including murder.
