Former porn star Bree Olsen - who once lived with Charlie Sheen as his sexual partner - has claimed she did not know he was HIV positive, despite the actor saying in a TV interview on Tuesday that all his former girlfriends know of his health status.

Just hours after Sheen gave his revealing interview to Matt Lauer on Today, Olson, 29, appeared on The Howard Stern Show telling a very different story.

She claimed that Sheen never told her that he was HIV positive, and she revealed that she was with him when he had his intense 'night sweats' - which can be an indicator of the disease.

'That was when I was with him. I was living with him. We were sleeping together every single night,' said Olsen. 'And he never said a word.'

Natalie Kenly, another of Sheen's 'goddesses', has come forward to say Sheen did not disclose his status to her either.

Olson (pictured leaving the SiriusXM radio station in New York today) claimed that Sheen never once revealed to her that he was HIV positive and that she was actually with him when he had his intense 'night sweats.'

Natalie Kenly, another of Sheen's 'goddesses', has come forward to say Sheen (pictured with Kenly in 2011) did not disclose his HIV status to her either

But Kenly told TMZ that she is not attacking for not disclosing his condition and does not intended to sue him. She added that she is HIV negative.

Olson, however, went on to say that Sheen insisted he was 'clean' (ie, he did not have any sexually transmitted diseases) and that he used lambskin condoms when they were together - which provide less protection than latex condoms.

Lambskin condoms are effective at preventing pregnancy, but do not prevent the transmission of viral STDs, including HIV.

Olsen said: ‘I didn’t want to use lambskin, I wanted to use regular condoms.

'I made the same mistake that a lot of people do, I trusted him.'

She added: ‘There were times when we didn’t use condoms, because it was only to prevent against pregnancy.

‘I loved him, yes, he was my boyfriend. I left the [porn] industry for him and I never went back.’

However, she also revealed she has been tested for HIV since discovering Sheen had it, and she has been given a clean bill of health.

But, of Sheen's alleged decision to not disclose his status, said said: 'It's illegal.'

If Sheen was aware he was infected at the time he was sleeping with Olsen, she would able to seek damages, and he could also be subject to criminal investigation.

In the state of California, it is a felony punishable by up to eight years in prison for a person to have unprotected sex with someone with the intent to infect them and not disclose their status.

It is also a misdemeanor to willfully expose someone to HIV, though that carries a prison sentence of just a few months.

This morning, Sheen revealed he is HIV positive in an explosive interview with Matt Lauer on Today.

'I'm here to admit that I am in fact HIV positive,' he said. 'It's a hard three letters to absorb. It's a turning point in one's life.'

WHAT ARE LAMBSKIN CONDOMS? Lambskin condoms, also known as sheepskin condoms or simply ‘skins’ are an alternative to the usual latex condoms. Skins are membrane condoms made from a thin layer of sheep cecum – a part of the animal's intestine. They are very thin and considered by many to provide the most pleasure of any type of condom. They provide increased sensation and present no problems for people who suffer from latex allergies. For pregnancy prevention, users consider them to be the closest thing to not wearing a condom at all. The lambskin material has tiny pores but they are not large enough to allow sperm to pass through. However, they are not effective against many sexually transmitted diseases. They do not prevent the transmission of viral STDs, including HIV and herpes, as the viruses are small enough to get through the pores. Advertisement

Sheen said that he learned he had the virus 'roughly four years ago' - but said that he was 'not entirely' sure how he contracted the virus and that he felt a huge sense of relief after publicly revealing his status.

His doctor, Robert Huizenga, said he had known Sheen for five or six years and that the virus is now 'undetectable' in his blood.

The actor said he was prepared to face lawsuits after his admission, and repeatedly told Lauer that he had always been honest about his status once he learned he had contracted the virus.

And TMZ reports that at least six women are planning to sue Sheen.

A Los Angeles lawyer told the site he had been contacted by the women today and has appointments with another four.

The woman claim they have had protected and unprotected sex with Sheen, some as recently as in October - but allege that he did not disclose this condition.

On Friday, amid rumors that the high-profile Hollywood star was living with HIV was Sheen, Olson took to Twitter to say she was ‘clean’.

'There are speculations circling that one of my ex boyfriends from years ago may have contracted the HIV virus,' Olson wrote.

'They are rumors and I know nothing more than anyone else.'

Olson continued: 'I, myself have been to my gynecologist at least once a year since we split up and have always been tested across the board for everything and have came back clean across the board every time.'

'For all the ''news'' sources out there, leave me alone. Call me Jon Snow. I know nothing.'

Her tweet came days before The National Enquirer released a story on Monday that the 50-year-old has been quietly battling a HIV diagnosis, after working on the piece for 18 months.

Hours after the story appeared online, People confirmed the news with crisis manager Howard Bragman.

And as the news broke, another ex-girlfriend, Natalie Kenly, gave an interview defending the actor.

Kenly said he only ever did right by the women who lived with him during his very-public meltdown in 2011, who became known as his 'goddesses'.

'He is not a monster,’ she told People. ‘He has regard for human beings and cares about people. I do not see him knowingly putting women at risk.'

Kenly also defended Sheen against suggestions that he had slept with women after learning of his diagnosis.

Olson tweeted this message on Friday and also posted on her personal website. She suggested that news outlets had been contacting her about her HIV status, but said she knew 'nothing'

'That's not who he is,' she told the magazine. 'He's got young kids. He's also not an idiot and I don't see him opening himself up to that legal nightmare.'

Kenly, who is now a mother and living in the Midwest with her partner, said she is HIV negative and has no regrets over the time she spent with Sheen.

'He's a good man and I feel very fortunate to have spent the time with him that I did, and I'm so sad to hear of his health troubles,' she added.

'I hope he's okay.'

Sheen and Olson met in 2011 after he contacted her out of the blue for a meet and greet at his house in Sherman Oaks, California.

'I suppose it was my movies,' she said, when asked what attracted Sheen to her.

The actress ended up leaving a break-up note for Sheen when he began paying less attention to her and more focused on his comedy tour.

Olson was one of Sheen's so-called 'goddesses' who lived with the actor in 2011 during his very-public breakdown and has starred in over 280 pornographic films

It said: 'C, I'm not comfortable here anymore. I'm going home. I wish you the best on the rest of your tour. (Here's your watch.)'

Sheen, who has had three wives, a number of fiancées and lived with various porn star 'goddesses' - has long enjoyed a playboy lifestyle and the Enquirer reported that his health has not slowed him down.

'Charlie had sex with multiple partners since learning his HIV status without informing them of his potentially deadly HIV infection,' a source told the Enquirer.

Another source said: 'Charlie hired escorts, and him being HIV positive never entered these women's minds.

'The fact is, he was playing Russian roulette with their lives, while the women were playing Russian roulette with the prospect of becoming pregnant by Sheen, and being set for life.'

The National Enquirer reported on Monday that Charlie Sheen is the mystery Hollywood star battling HIV

The Enquirer also reported that one of the women who was allegedly exposed settled a civil action against the actor after retaining Gloria Allred as her lawyer.

Sheen has been married three times and has five children - a daughter Cassandra, 21, with high school sweetheart Paula Profit; daughters Sam, 11, and Lola, 10, with second wife Denise Richards; and twin boys Bob and Max, six, with third wife Brooke Mueller.

He had been engaged to be married to adult film star Scottine Ross, also known as Brett Rossi, but the engagement was called off in October last year after eight months.

In a video obtained by the Enquirer, Ross is reportedly seen screaming about Sheen: 'You exposed me to HIV for a year and a half!'

An insider claimed: 'Sheen waited over four months to inform Scottine that he was HIV positive.

‘From the very beginning, Sheen never used protection, saying he 'loved' her.'

Sheen had reportedly spent $5million to keep the news that he had HIV 'silent,' but despite this, it became an 'open secret' to many in Hollywood.
