Sharon Stone has revealed for the first time that she was physically assaulted years ago by an unnamed perpetrator, claiming that a doctor discovered evidence of a “felony” crime during a medical exam.

During a wide-ranging interview on a new episode of The Person Who Believed in Me podcast hosted by CBS correspondent David Begnaud, Stone launched into the story after detailing how a cancer scare led to the demise of her marriage to newspaper editor Phil Bronstein.

“I don’t know how much I can tell about this. I was hit from behind,” Stone said. “I didn’t really know until 10 years later what had happened to me because I woke up. I was unconscious on the floor. The two couches were sideways. The coffee table was all over the place. It was sort of upside down. Everything that had been on the coffee table was all over the floor and I didn’t know how I got there.”

The veteran star said the dramatic scene was brought to her attention a decade later while visiting a doctor. “I went to a clinic because I was having a lot of problems with the back of my neck and my shoulders were so sore and I went to a neck and spine clinic in Marina Del Rey and they had given me propofol and they’d done a lot of X-rays of my front and back and all this stuff. They were going to do some kind of injections into what they thought was arthritis in my neck and shoulders, and they had done all these preliminary x-rays of my thoracic rib cage and my neck and my shoulders and my spine and the doctor came in and he’s like, ‘We’re not going to be able to do this surgery.’ I was like, ‘I don’t know what you’re talking about.’ And he’s like, ‘Your thoracic rib cage is all fractured and scarred back together. It’s clear that you were attacked and that what happened to you was a felony.'”
