Michael Douglas has revealed he had another secret romance with one of his co-stars.
The confession comes just days after admitting he and Kathleen Turner had hidden their relationship for more than 40 years.
This time, the actor has opened up about what happened behind the scenes of his famously steamy 1992 thriller Basic Instinct.
He had incredible chemistry with Sharon Stone, which caused years of rumours.

It turns out though, it wasn't actually Stone who caught his eye.
Douglas, 82, has revealed in his new memoir One Helluva Ride that he became romantically involved with actress Jeanne Tripplehorn, who played Dr Beth Garner in the film.
Tripplehorn was making her film debut in Basic Instinct, playing police psychologist Beth and the former girlfriend of Douglas' character, Detective Nick Curran.
She was in her late 20s at the time, while Douglas was 47.

“The truth is, I fell very hard for Jeanne despite our nearly 20-year age difference,” wrote the star.
Douglas has now revealed that the pair became close during filming in San Francisco, although they managed to keep their relationship hidden from those working on the movie.
At the time, Douglas was still married to his first wife, Diandra Luker, however, the couple were separated.
According to Douglas, he and Tripplehorn began spending more time together after work, and what started as friendship developed into something more serious.
The actor admits in his memoir that he ‘fell hard’ for Tripplehorn and was even considering leaving his marriage behind for good.
Things became considerably more complicated when Douglas and Tripplehorn had to film intimate scenes together.
Their relationship ultimately didn't last beyond the production.
“But I will always think of her as an amazing actress and a truly terrific woman that I was very fortunate to spend time with,” he wrote.
Douglas has explained that, although he cared deeply for Tripplehorn, he realised he wasn't ready to immediately jump into another serious relationship while his marriage was falling apart.
Tripplehorn reportedly gave Douglas her blessing to include their relationship in his memoir.
She later married actor Leland Orser in 2000.
Given Basic Instinct's reputation, it's perhaps unsurprising that people have spent years wondering whether Douglas and Stone's extraordinary on-screen chemistry ever spilled over into real life.

The erotic thriller became notorious for its sex scenes after its release in 1992, while Stone's performance as crime novelist Catherine Tramell turned her into one of the biggest stars of the decade.
The admission follows another surprising revelation from Douglas about Romancing the Stone co-star Kathleen Turner.
Douglas revealed that he and Turner ‘fell hard for each other’ while making the 1984 adventure film in Mexico and secretly began a relationship.
The pair had previously maintained for decades that, despite their obvious chemistry, nothing actually happened between them.
Douglas has now admitted that wasn't true.
“It was a lie meant to protect my wife and son, a lie we told the world for 40 years,” he wrote.
He explained that they became friends, co-stars and eventually lovers, with Douglas secretly visiting Turner's hotel room after their colleagues had gone to sleep.
Their romance ended after Diandra visited the set with Cameron and spoke to Turner about their marriage.
Turner subsequently decided she didn't want to interfere, while Douglas reconciled with his wife.
Looking back, he admits the reconciliation was a mistake.
Turner, meanwhile, seems considerably less shocked by the whole thing becoming public.
Responding to the headlines, she joked: “Good heavens what a fuss about something 40 years ago!”
Douglas went on to marry Catherine Zeta-Jones in 2000.
