Michael Douglas Confesses to Affair With Kathleen Turner After Decades of Rumors

Michael Douglas is releasing a decades-long secret.

Over forty years after he and Kathleen Turner raised eyebrows with their onscreen chemistry in the 1984 film Romancing the Stone, Douglas—who was separated but still legally married to Diandra Luker at the time—admitted that he and his costar did engage in an affair after denying it for years.

Douglas, who has been married to Catherine Zeta-Jones since 2000, describes meeting Turner in his new memoir One Helluva Ride, detailing their mutual immediate attraction.

“The chemistry I had with Kathleen Turner was so strong, audiences have been certain for years that we were in a relationship together while making the film,” he writes in the book, out Oct 6, according to an excerpt published by People. “The official story went as follows: Yes, we confessed, we had amazing chemistry. Yes, we were both, as Kathleen said, ‘terrible flirts,’ and yes, we were both tempted, but nothing ever happened between us.

But, as he noted, “That was a lie.”

According to the 82-year-old, the pair lied to protect his then-wife Luker, with whom he shares son Cameron Douglas.
