Bree Olson and Charlie Sheen

Bree Olson and Charlie Sheen

*Moments after Charlie Sheen confirmed his HIV-positive status on the “Today” show Tuesday, one of his ex-girlfriends is refuting the actor’s claim that he disclosed his condition to all of his past sexual partners.

Former porn star Bree Olson, whose real name is Rachel Oberlin, lived with Sheen in 2011 as one of the “goddesses” in his Los Angeles home following his public meltdown and firing from “Two and a Half Men.”

She hit up The Howard Stern Show Tuesday morning shortly after the actor, 50, revealed to “Today’s” Matt Lauer that he was diagnosed with HIV about four years ago. Olson said his claim that he told everyone of his sexual partners about his status – before he engaged in sex with them – is “bulls**t.”

“I watched, right before I came in here … the interviewer asked him: ‘Was this during the tiger blood thing, is this because of that?’ And he even admittedly said, he’s like: ‘Well, I don’t know if it’s necessarily because of that,’ ” Olson told Stern. “So he just admitted right in that interview that is the tiger blood time – that’s when I was with him! I was living with him! We were sleeping together every single night.”

When Stern asked if Sheen ever told her about his diagnosis, Olson vehemently denied him ever saying anything about it.

“Never said anything. Ever. ‘I’m clean,’ he told me. ‘I’m clean, I’m clean.’ ”

Olson also told Stern that she has tested negative for HIV.
