Charlie Sheen’s ex Bree Olson is speaking out against the actor, claiming he did not tell her about his HIV diagnosis, and alleging that he had unprotected sex with her after learning that he was HIV positive.

“I could be dead right now,” the 30-year-old former adult film star told Inside Edition after Sheen confirmed reports that he was HIV positive on the Today show on Tuesday. “It was like playing Russian Roulette, that’s the best way to put it. It was like he was putting a gun to my head and pulling the trigger each time.”

Olson was one of Sheen's live-in “goddesses” during his legendary 2011 meltdown, the same year the actor lost his role on Two and a Half Men, though the timeline of the pair’s relationship in regards to when Sheen found out he was HIV positive is murky. The 50-year-old actor told Matt Lauer that after learning of his diagnosis roughly four years ago, he’s told every sexual partner since that he is HIV positive. Olson reportedly left Sheen in April 2011.

ET has reached out to Olson to clarify the chain of events.

“He says that he found out when him and I were together, I was living in his house,” Olson claimed. “There is no one he could have trusted more to confide this information in than to me.”

The former porn star said during the time that she and model Natalie Kenly lived with Sheen, the actor would take mysterious phone calls from physicians. She told Howard Stern on Tuesday that a doctor frequently came to the house and would go with Sheen into another room for privacy.

“He would come out of the room, and kiss me and hug me like nothing,” Olson said of the alleged visits. “And then, sex again that night. We had sex every night for a full year.”

Sheen told Lauer that there’s no way he could have transferred the virus to any other person since his diagnosis, calling it “impossible.” Olson claims that the actor is “lying,” saying that she and Sheen had unprotected sex “many times.”

“He used this word ‘I’m clean,’” she added. “And I know, but I believed him.”

After hearing rumors of Sheen’s HIV diagnosis through the media, Olson recorded herself on her cell phone going to get tested and learning that she is HIV negative.

“I would never do to anyone what Charlie did to me,” she said tearfully. “That is giving someone a possible death sentence. I would never do that to someone, ever.”

When asked why she thought her ex allegedly kept the information from her, Olson simply answered that she believes Sheen “doesn’t care.”

“There’s nothing that man could say to me,” she said. “He’s a monster.”
