Charlie Sheen is facing a number of lawsuits and being attacked by former partners after revealing he is HIV-positive.

Just hours after Sheen told Matt Lauer on Today that he has had the virus for 'roughly four years' and informed all of his sexual partners since that time, the actor's former girlfriend Bree Olson made an appearance on The Howard Stern Show telling a very different story.

She claimed that Sheen never once revealed to her that he is HIV-positive, and said later in a separate interview; 'He's a monster.'

Shortly after Olson appeared on Stern's show another one of Sheen's sexual partners, Natalie Kenly, came forward to say that the actor never told her either that he is HIV-positive.

Sources close to Sheen tell TMZ that he did not find out he is HIV-positive until May 2011, at which time he was no longer with Olson - though he was still dating Kenly.

Charlie Sheen confirmed he is HIV-positive in an interview with the Today show's Matt Lauer Tuesday morning

Sheen's ex Bree Olson (left on Tuesday) is claiming he never once told her he was HIV positive, a claim that is also being made by his ex Natalie Kenly (right with Sheen in May 2011)

'He's a monster,' said an emotional Olson in an interview with Inside Edition on Tuesday

'I could be dead right now! I could literally be dead right now because he did not tell me that!' said Olson on Inside Edition in a two-part interview that will air on Tuesday and Wednesday nights.

She then added; "He says he found out when him and I were together. I was living in his house. We were having sex every single night.'

Olson, 29, went on to say that Sheen even went so far as to tell her he was 'clean,' and used lambskin condoms when they were together, which provide less protection than latex condoms and do not protect against viral sexually transmitted diseases such as HIV.

I could be dead right now! I could literally be dead right now because he did not tell me that! - Bree Olson

'He used this word: I'm clean. I'm clean and - I know... but I believed him,' said Olson.

'It was like playing Russian Roulette. That's the best way to put it. It was like putting a gun to my head and pulling the trigger each time.'

Olson later said in the interview; 'I would never do to anyone what Charlie did to me. That is giving someone a possible death sentence. I would never do that to someone ever.'

As for her message to Sheen, she said; 'Charlie, you're a terrible person. You're a terrible person. I will never forgive you.'

She was tested on Monday and is not HIV-positive.

Kenly and Olson were both with Sheen at the same time, and he referred to the women as his 'goddesses.'

Kenly told TMZ she is not HIV-positive and is not upset with Sheen. She also said that she does not plain to file a lawsuit against the actor.

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.

TMZ is reporting that already six of Sheen's former sexual partners are planning to sue the actor for 'intentional infliction of emotional distress, fraud, sexual battery.'

Some of these women are alleging they have had both protected and unprotected sex with Sheen as recently as a month ago.

Radar Online meanwhile has spoken to a source close to an attorney who said one individual had had sex just this past week with Sheen, and that he did not reveal his status.

'And a second individual claims they had sex with Charlie three weeks ago,' said the source.

'All of these people say they were not notified by Charlie about his HIV status and now they want settlements.'

InTouch obtained the non-disclosure agreement that Sheen makes guests at his house sign.

If an individual breaks the agreement it states they must pay Sheen $100,000, and a percentage of any money they may have received for the information they shared.

The document also states that any matter will be decided by an arbitrator - and not in a court of law.

'I would never do to anyone what Charlie did to me. That is giving someone a possible death sentence. I would never do that to someone ever,' said Olson

Sheen told Matt Lauer that he had told people that he trusted his status over the past few years, but also bought the silence of others

Already, six of Sheen's former sexual partners are planning to sue the actor for 'intentional infliction of emotional distress, fraud, sexual battery'

His doctor, Robert Huizenga, said on Today that the virus is now 'undetectable' in Sheen's blood, but that does not mean he is incapable of infecting other people..

Sheen also 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.

'It started with what I thought was a series of crushing headaches and insane migraines and sweating the bed completely drenched, two, three nights in a row,' said Sheen of his first symptoms.

In and around this perplexing and difficult time I dazedly choose or hired the companionship of unsavory or insipid types. Regardless of their saltless reputations, I always led with condoms and honesty when it came to my condition. Sadly, my truth soon became their treason as a deluge of blackmail and extortion took center stage in this circus of deceit.

'I was emergency hospitalized. I thought I had a brain tumor. I thought it was over.

'After a battery of tests ... they walked in the room and said "BOOM. Here's what's going on."'

Sheen said that he had told people that he trusted his status over the past few years, but also bought the silence of others.

'I have to put a stop to this onslaught, this barrage of attacks and of sub-truths and very harmful and mercurial stories that are about me, that threaten the health of so many others that couldn't be further from the truth,' said Sheen about his decision to go public with his status.

'We're talking about shakedowns,' Sheen said of some of the people he had been forced to pay to keep quiet.

'I have paid those people. Not that many, but enough.

'I don’t want to guess wrong, but enough to bring into the millions. What people forget: that’s money they’re taking from my children; I’ve got five kids and a granddaughter.'

In a letter to Lauer written before his appearance, Sheen said of his life after learning of his diagnosis; 'In and around this perplexing and difficult time I dazedly choose or hired the companionship of unsavory or insipid types.

'Regardless of their saltless reputations, I always led with condoms and honesty when it came to my condition.

'Sadly, my truth soon became their treason as a deluge of blackmail and extortion took center stage in this circus of deceit.'

Sheen said that many of the people he was referring to in that letter did not have sexual contact with him, but rather discovered his status and threatened to reveal it to the world.

'For some reason I trusted them, they were deep in my inner circle and I thought that they could be helpful,' said Sheen.

'And instead, as I wrote in my letter, my trust turned to their treason.'

Sheen's doctor, Robert Huizenga, later said he had been working with Sheen for five or six years and that the virus is now 'undetectable' in his blood

Sheen (seen getting in his car after his interview on Today) said he was diagnosed as HIV positive 'roughly four years ago'

Sheen admitted to Lauer that at one point a prostitute came to his home and after a sexual encounter took a photograph of his antiviral medication. She then threatened to sell it to the tabloids.

'After I told her, "Thank you for your time, we're not going to see each other any more,"' explained Sheen.

'It was after she spent the day at the health food store buying me herbal medications to help me.'

When asked if he was still paying anyone for their silence, Sheen said; 'Not after today I'm not.'

He then said; 'I think I release myself from this prison today.'

Lauer then asked Sheen why he continued to cavort with 'unsavory' characters even after some were able to successfully extort him.

I was so depressed by the condition I was in I was doing a lot of drugs. I was drinking. And I was making really bad decisions.

'Because I was so depressed by the condition I was in I was doing a lot of drugs. I was drinking. And I was making really bad decisions,' said Sheen.

'That part I own. 100 percent.'

He also said it was 'impossible' that he had transmitted the virus to anyone else and that he had informed every partner he has had that he is HIV positive.

When asked if he had engaged in unprotected sex since being diagnosed with the virus Sheen admitted that he had with two partners, but that the individuals were aware of his status and under the care of his doctor.

PrEP ( pre-exposure prophylaxis) pills can be taken by men and transgender women who have not been exposed to HIV to help them prevent becoming infected by a sexual partner.

Lauer then asked Sheen is he had engaged in any other 'risky behaviors' over the past few years.

'Negative. No, you're talking about needles and that whole mess. No. Definitely not,' said Sheen.

In another passage from the letter Sheen wrote to Lauer, the actor said of the his state after being diagnosed; 'The personal disbelief, karmic confusion, shame and anger led to a temporary yet abysmal descent into profound substance abuse and fathomless drinking.'

Lauer asked if Sheen's behavior in early 2011 when he did a slew of interviews with almost every major network in which he claimed to have 'tiger blood' and be a 'ninja assassin from Mars' was a result of learning about his diagnosis.

'I wish I could blame it on that but that was more of a 'roid rage,' said Sheen.

'But this was on the heels of that I would say.'

'It started with what I thought was a series of crushing headaches and insane migraines and sweating the bed completely drenched, two, three nights in a row,' said Sheen of his first symptoms

Sheen (seen leaving his hotel on his way to Today) said it was 'impossible' that he might have in infect any of his partners with the virus

The actor was then joined by his doctor who explained what Sheen's diagnosis meant for his health moving forward.

'Charlie has contracted the HIV virus,' said Huizenga.

'He was immediately put on strong antiviral drugs which have suppressed the virus. Unfortunately, we don't have a cure yet.

WHAT IS ANTIRETROVIRAL THERAPY? Antiretroviral therapy (ART) consists of the combination of at least three antiretroviral (ARV) drugs to maximally suppress the HIV virus and stop the progression of HIV disease. Huge reductions have been seen in rates of death and suffering when use is made of this type of treatment, particularly in early stages of the disease. Since 2013, WHO also recommends the use of antiretroviral drugs for the prevention of HIV infection, particularly for pregnant women, young children, and key populations exposed to HIV risk.

'It has suppressed the virus to the point that he is absolutely healthy from that vantage and my biggest concern with Charlie as a patient is substance abuse and depression from the disease more than what the HIV virus could do in terms of shortening his life.'

He then firmly stated that Sheen does not have AIDS.

'He is healthy. He does not have AIDS,' said Huizenga.

Speaking of the possibility of Sheen infecting others with the virus Huizenga said; 'Individuals who are optimally treated, who have undetectable viral loads, who responsibly use protection, it's incredibly low. It's incredibly rare to transmit the virus.'

Sheen also said that he is not longer doing drugs at this time, and taking four pills a day as part of his drug cocktail to fight the virus.

He did admit that he is still drinking a little bit.

'We're petrified about Charlie. We're so, so anxious,' said Huizenga is reference to the actor's lapses in the past with drugs and alcohol.

'If he was overly depressed, if he was abusing substances he would forget these pills. That's been an incredibly worry.

'And magically somehow in the midst of incredible personal mayhem he's managed to continue to take these medications.'

Sheen then said that since being diagnosed he has never once missed taking his medication.

Approximately 1.2 million people in the United States are living with HIV.

Sheen said he was prepared to face lawsuits after his admission, but repeated once again he had always been honest about his status with his partners

Sheen said he was prepared to face lawsuits after his admission, but repeated once again he had always been honest about his status once he learned he had contracted the virus.

'I mean I would be predicting the future and assuming the worst. I can only imagine based on what I've already experienced, what's already come down the pike and I've been forced to deal with, I'm sure that's next,' said Sheen.

Lauer then asked Sheen is he was nervous about the possibility of facing criminal charges, noting that in 35 states an individual can be charged if they engage in sexual activity with someone but do not divulge the fact that they are HIV positive.

I'm not going to be the poster man for this, but I'm not going to shun away from responsibilities and opportunities that drive me to helping others and delivering a cure.

Sheen told Lauer that he had in fact divulged his status, pointing out that his honesty about being infected is why he was forced to pay millions to but the silence of multiple individuals.

Talk then turned to Sheen's financial situation, which he said was 'not great.'

'It'll be great again. I'm a survivor,' said Sheen.

'I've been up, I've been down. I've been rich, I've been poor ... It's another chapter in my life that's not commerce driven but it's socially driven.'

He also said that he had told his oldest daughter Cassandra a few nights before the interview that he was HIV positive and that his ex-wives Denise Richards and Brooke Mueller had known for years.

Mueller's rep told US Weekly on Tuesday that neither she or her twin boys are HIV-positive.

Richards had previously stated that she and Sheen have had no sexual contact since they split in 2005.

'I told my oldest daughter Cassandra the other night and I felt bad,' said Sheen.

'It hit her hard and she recovered. She's tough like her dad. And she said, "Wow."'

Sheen then got a bit choked up before he continued to describe their conversation, saying; 'I'm sorry I didn't tell you sooner, it didn't seem like you could do anything for me and I didn't want to burden you with all the stress.

'But she was a rockstar about it.'

He did not say if he had told his four youngest children.

TMZ is reporting his daughters with Denise Richards - 11-year-old Sam and 10-year-old Lola - did not know their father was HIV-positive, and were 'blindsided' when he revealed the news on Tuesday.

'I've been up, I've been down. I've been rich, I've been poor ... It's another chapter in my life that's not commerce driven but it's socially driven,' aid Sheen of his future

Lauer asked Sheen what he thought the headlines would be after making this bombshell admission.

'I mean you can never really predict how the media's gonna roll with something,' said Sheen.

'I mean, I would hope, or I would have faith, a lot more forgiving and a lot more supportive then some of the garbage I was reading in the last couple of days.

Frankly, I don't think it can get any worse.'

The talk then turned to reports that Sheen may have knowingly infected individuals, and Lauer brought up reports that some of Sheen's former partners said he did not reveal his status.

If there was one guy on this planet to contract this that's gonna deliver a cure it's me.

'They're gonna have to reveal a whole lot of proof because it's just not there,' said Sheen of these claims.

'It doesn't exist.'

When asked if he had been successfully sued or settled a lawsuit over the past few years as a result of having the virus, Sheen said; 'Not for any contamination. Not for any transference.But just for threats of revealing my condition.'

After Lauer showed Sheen the support he was getting for the interview on social media, the actor said; 'I'm gonna ride this wave of support and if there was one guy on this planet to contract this that's gonna deliver a cure it's me.'

He quickly added however; 'I'm not going to be the poster man for this, but I'm not going to shun away from responsibilities and opportunities that drive me to helping others and delivering a cure.'

Moving forward Sheen said; 'I have a responsibility now to better myself and to help a lot of other people and hopefully with what we're doing today others will come forward and say, thanks Charlie.'

He also spoke about work, saying he had the chairman of Sony excited excited about a project and a couple of films lined up in the future.

Sheen said in private conversations prior to Tuesday's interview those involved with these projects had no issue with him publicly revealing the fact that he was HIV-positive.

'Thus far there's been no resistance,' said Sheen.

Lauer closed by asking about how far down the road Sheen was with battling his personal demons, last seen very publicly in 2011.

'I think very far down the road. There's a lot about that period I'm not proud of,' said Sheen.

'You can only hear winning in the street so many times. I pissed off a lot of really good opportunities. But like I said, I'm approaching a time of more of a philanthropic approach in my life.'

Shortly after his interview on Tuesday, it was reported that Sheen was unloading two of his multi-million dollar California mansions.

Variety reports that the actor is selling 'a 6,625-square-foot semi-Spanish villa he acquired up in October 2012 for $4.8 million' and 'his 9,020-square-foot mock-Mediterranean with six bedrooms and nine bathrooms that he picked up in March 2011 for $6,999,999.'

They did not say how much the properties were being listed for, and said that Sheen will keep his '7,924-square-foot mansion he bought in April 2006 for $7.2 million.'

CHARLIE SHEEN'S OPEN LETTER ABOUT BEING HIV POSITIVE 'Roughly four years ago, I suddenly found myself in the throws of a seismic and debilitating three-day cluster-migraine-like headache. I was emergently hospitalized with what I believed to be a brain tumor or perhaps some unknown pathology. I was partially correct. Following a battery of endless tests, that included a hideous spinal tap, it was sadly and shockingly revealed to me that I was, in fact, positive for HIV. 'The news was a "mule kick" to my soul. Those impossible words I absorbed and then tried to convince myself, that I was stuck, suspended, or even stranded inside some kind of alternate reality or nightmare, were to the absolute contrary. I was awake. It was true… reality. 'Under the brilliant and perfect care of Dr. Robert Huizenga as well as "the" leading infectious disease expert in the known universe, I began a rigorous and intensive treatment program. Not missing a beat, a med dose, or one shred of guidance, quickly my viral loads became undetectable. Like every other challenge in my life, again, I was victorious and kicking this disease's ass. I wish my story had ended there. Unfortunately, for my family and myself, it had only just begun. 'The personal disbelief, karmic confusion, shame and anger lead to a temporary yet abysmal descent into profound substance abuse and fathomless drinking. It was a suicide run. Problem was, I'd forgotten that I'm too tough for such a cowardly departure. Yet, despite this loathsome and horrific odyssey, I was vigilant with my anti-viral program. 'My medical team could only shake their heads as each and every blood test returned levels revealing a state of remission. Even though I might have been trying to kill myself, one thing was radically evident; the disease was not. 'In and around this perplexing and difficult time, I dazedly chose (or hired) the companionship of unsavory and insipid types. Regardless of their salt-less reputations, I always lead with condoms and honesty when it came to my condition. Sadly, my truth soon became their treason, as a deluge of blackmail and extortion took center stage in this circus of deceit. 'To date, I have paid out countless millions to these desperate charlatans. 'Locked in a vacuum of fear, I chose to allow their threats and skulduggery to vastly deplete future assets from my children, while my "secret" sat entombed in their hives of folly (or so I thought). 'News Flash: This ends today. I'm claiming back my freedom. The scales of justice will swiftly and righteously re-balance themselves. 'In conclusion, I accept this condition not as a curse or scourge, but rather as an opportunity and a challenge. An opportunity to help others. A challenge to better myself. 'Every day, of every month, of every year, countless individuals go to work, man their stations, fulfill their professional obligations with a host of disabilities. Diseases, imperfections, hurdles, detours. These maladies range from lupus to cancer, from paralysis to blindness, from diabetes to obesity. "Treated," HIV is no different. 'My partying days are behind me. My philanthropic days are ahead of me. 'Ernest Hemingway once wrote, "Courage is grace under pressure." 'I've served my time under pressure; I now embrace the courage, and the grace. 'Love and peace,Charlie Sheen' - TODAY Advertisement

The National Enquirer was the first to report that Sheen is HIV positive, a story they have worked on for 18 months, and two hours after they released their story People confirmed the news with crisis manager Howard Bragman.

Charlie - who has had three wives, additional fiancees and lived with various porn star 'goddesses' - has long flouted traditional ways.

Sheen has been married three times and has five children - a daughter Cassandra, 30, with high school sweetheart Paula Profit; Daughters Sam, 11, and Lola, 10, with second wife Denise Richards; and twin boys Bob and Max, 6, 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 2014 after eight months.

An email that was released in the wake of the Sony hack from March of 2014 included a link to an article reporting that Sheen was having trouble on the set of his show Anger Management, and the sender wrote 'it's hard to to be a drug addict and be HIV positive and do 40 eps a year.'

He was once the highest paid actor on television, earning a reported $1.8million per episode for his work on Two and a Half Men during the show's eighth season.

The actor has had numerous problems with drugs and alcohol over the years, and was ultimately fired from his role on Men when he demanded more money for his work following his third stint in rehab in a 12-month period.

Born Carlos Estevez, Sheen is the son of actor Martin Sheen and brother of Emilio Estevez.

His acting career began in 1984 when he starred in the film Red Dawn, and he would go on to star in such classics as Ferris Bueller's Day Off, Platoon, Wall Street and Major League.

In a bizarre incident in 1990, Sheen's fiance Kelly Preston was shot in the arm when his gun accidentally fired while she was picking up a pair of his pants and shrapnel or porcelain from where the bullet hit the toilet bowl grazed her arm.

The incident was reportedly an accident, but Preston called off their engagement soon after.

It was revealed a few years later in 1995 that Sheen was a client of the escort agency run by Hollywood madam Heidi Fleiss.

He was married that same year to model Donna Peele, but the two divorced after just five months.

The actor suffered a stroke three years later in 1998 after injecting himself with cocaine and overdosing on the drug, something he admitted to in a 2004 interview with The Telegraph.

He entered rehab soon after the incident but left almost immediately, but a few months later entered a program and was reportedly clean for years.

He was arrested in 2009 after assaulting Mueller on Christmas day in Aspen. Mueller told police that Sheen placed a knife to her throat and threatened to kill her when she asked for a divorce.

Sheen allegedly said to Mueller; 'You better be in fear. If you tell anybody, I'll kill you. I have ex-police I can hire who know how to get the job done and they won't leave any trace.'

He eventually pleaded guilty to misdemeanor assault and received 30 days in a drug rehab center, 30 days of probation, and 36 hours of anger management.

Less than a year later in October 2010 Sheen caused $7,000 in damage to his room at New York's Plaza Hotel after a night of drinking and doing cocaine.

Sheen had just a week left on probation when the incident occurred. The escort who was with Sheen at the time said she locked herself in the bathroom she was so afraid of the actor.

Richards, who was staying across the hall from him at The Plaza with their two daughters, had staff at the hotel call the police and later accompanied Sheen to the hospital where he underwent a psych evaluation.

Sheen was never charged with a crime for the incident, though the woman with him, Capri Anderson, later sued him claiming he choked her.

SOCIAL MEDIA REACTIONS TO CHARLIE SHEEN'S HIV DIAGNOSIS Actress Heather Locklear was one of the many taking to social media to voice their support for Charlie Sheen, as it was revealed the actor was HIV positive. The 50-year-old confirmed rumors that he was the mysterious Hollywood actor keeping the disease private in a bombshell Today show interview on Tuesday. Just hours before the revealing interview, Locklear posted a picture of herself with Sheen on Instagram, writing: 'My heart hurts. Prayers for Charlie and his family'. Supporter: Heather Locklear was one of the first celebrities to speak out about Charlie Sheen's HIV diagnosis As Sheen made the announcement Tuesday morning, Twitter users were mostly supportive of the actor's decision to come out and speak about his diagnosis. 'Above all Charlie Sheen you are a child of God. Your bravery will save lives,' Twitter user @DUNBAR83 wrote. However, others were more judgmental - saying the diagnosis wasn't surprising considering the actor's public breakdown and descent into alcohol abuse. 'The same lifestyle Charlie Sheen was living on Two and a half men, he was living in reality, they say.. Hence, he is HIV +' Twitter user @Tasheek_M wrote. Advertisement

Taking its toll: Sheen's years of partying have taken a bit of a toll on the actor's teeth (above in November 2011)

Sheen was arrested in 2009 in Aspen on Christmas after an incident between him and Mueller (left); Mueller was arrested almost two years later to the day in Aspen for assault and possession on cocaine (right)

He was back at it again in January 2011, going on a bender in Las Vegas that resulted in him missing work on Two and a Half Men. Two weeks later he went to the hospital suffering severe abdominal pain, and the next day checked into rehab.

That March, after being forced to cut their season short because of Sheen's problems, Warner Brothers terminated the actor from his contract.

Soon after, Sheen went on a nationwide tour he called Violent Torpedo of Truth/Defeat Is Not An Option.

This is also when Sheen began dating his 'goddesses,' Olson and Kenly.

Olson, wrote on Twitter Monday; 'Recorded myself for half an hour being tested for HIV and getting the results. This is so stressful.'

Sheen later apologized for his behavior in early 2011, saying he did not recognize himself.

He began work in 2012 on Anger Management and also appeared in cameo roles in films including Machete Kill and Scary Movie 5 alongside Lindsay Lohan.

In Scary Movie, Lohan and Sheen play themselves as troubled stars with past drug and alcohol issues who are making a sex tape.

The past few years have been seemingly uneventful for Sheen, save a few vicious Twitter attacks on ex-wife Richards who he seems to always reconcile with in the end.
