Charlie Sheen's PA reveals the life with the out-of-control star...

High on drugs and amid a heavy drinking session, a shirtless Charlie Sheen played with a large knife inside his 'party den', showing off to his audience of paid-for porn stars and friends.

Then, as the crack cocaine and alcohol finally took their toll, the Hollywood superstar made a slip with the blade, slashing his own leg causing blood to pour out.

It was perhaps a worryingly typical moment for the renowned hard-partying star who's high octane lifestyle had begun to spiral out of control in 2011.

But this time something else was wrong.

As blood spattered on to the plush carpet and on to an iPad, one of Sheen's friends jokingly lunged forward to touch the bright red bodily fluid, shouting 'that's tiger blood, Charlie that's tiger blood'.

The friend was trying to make light of the accident, while referencing Sheen's own claim that he had 'tiger blood' coursing through his veins.

But Sheen stopped him dead, screaming: 'Don't touch my blood, don't touch my blood, I got this.'

The friend recoiled in shock, not quite understanding why Sheen had reacted so angrily.

For Sheen's personal assistant and close friend Steve Han, who witnessed the incident in mid 2012, it was the first sign that something was seriously wrong.

'It was such a strange reaction, he seemed genuinely concerned that someone might actually touch his blood,' Han told Daily Mail Online in a world exclusive interview.

'We were partying in the party den, a room just off his bedroom, and we all blew his reaction off because we were in the midst of a wild night, but I knew deep down something was wrong, I could see it in his eyes.

'At the time I thought maybe he's got Hep C or something, but I never imagined it was much worse.

'I knew he was dealing with something major but couldn't put my finger on it.'

What Han didn't know was that Sheen was harboring a painful secret few people were privvy to - the year before Sheen had been diagnosed HIV positive.

And in an exclusive interview Sheen's assistant of two-and-a-half years reveals his former employer's torture as he tried to deal with the secret burden of carrying the virus, how he confided in only a handful of his 'inner circle' and how the star was bombarded by threats of lawsuits from girls desperate to cash in on his dark secret.

This comes a week after Sheen - amid a maelstrom of rumor and speculation - made the shocking admission to Matt Lauer on the Today Show that he is HIV positive.

Han, 34, who began to work for Sheen in early 2011 and traveled the world with him, recalls the emotional moment his boss confided in him about being HIV positive, saying, 'I f***ed up'.

'I remember we had been down to Cabo in Mexico on a trip in December 2012.

'There was a group of us: me, Charlie, porn star Georgia Jones, two other girls, a couple of friends and security.

'The plan was to spend New Year's Eve in Cabo at a private villa but we wanted to fly back early to avoid a storm and we got back to LA the night before.

'We celebrated New Year's at Charlie's house instead, just a small gathering.

'I remember I had got in to some drama with one of Charlie's body guards, he had been giving me a hard time and it upset me.

'That night Charlie took me to one side to ask what was wrong.

'We were sitting at his kitchen table and I unburdened myself and got a bit emotional, I told him all my problems.

'We were just being very honest with each other, I was explaining my feelings towards what was wrong with the body guard and he just started to talk about his problems and said life isn't perfect.

'Then he just came out with it, 'I'm HIV positive', he was so blasé about it.

'I was shocked. He was sad to have to tell me, he didn't want to tell me, he wanted to empathize with me.

'He was very strong about it, he said 'it's okay, don't cry, I'm not dying, things will get better.'

'He wanted to reassure me that he's got the right doctor and he was being looked after. For him it isn't a death sentence.

'I felt horrible, I felt like I knew a secret that only a handful of people knew on this entire planet.

'At that moment I didn't care about the body guards any more.'

Han said he asked Sheen if he knew how he'd contracted HIV but the star simply responded: 'I f***ed up'.

 The former assistant says the revelation brought him and the former Two and a Half Men star closer together as friends and he promised to help his boss through the difficult time.

'I felt closer to him, I felt like we were better friends after that,' Han said.

 Han says he took charge of making sure Sheen took his medication and would leave three anti-viral pills in Sheen's bathroom every night for him to take the following morning.

'I would wake him up in the morning, make Charlie a coffee the way he likes it, black, two scoops of sugar and then either text him or knock on his door,' he said.

'If the pills had gone then I knew he had taken them, I knew it was important that he didn't miss any days. Sometimes I would physically hand the meds to him, putting them in his mouth. He always expressed his displeasure.'

 Han said taking the anti-viral pills was a huge chore for Sheen and they made him feel constantly sick.

'The pills had side effects, he would feel nauseous and would skip meals, he's not a pill guy at all,' he said.

He was paying $1,500 a day for a private chef but the meals would go untouched, sat in the refrigerator wrapped in foil.'

Han would regularly pick up brown paper bags with Sheen's pills inside from the office of his personal physician Dr Robert Huizenga.

He also scheduled blood tests for the actor - star of hit movies including Wall Street, Platoon and Major League.

'A nurse came round to the house to take his blood,' he said. 

'I remember the first blood test I scheduled was in February 2013 and it came back showing the HIV was undetectable. Charlie was very happy.'

Buoyed by the test results, Han said Sheen continued life as normal, including his party lifestyle.

The assistant said he often joined in on the partying but his involvement stopped short of having sex with any of the porn stars that littered Sheen's $7.5 million Beverly Hills mansion.

'It was Charlie's money so I would hang out in a different room with anyone else who was at the party and we'd leave him to it,' he said.

'Sometimes he would miss the tests, I would have to get the nurse to come to hotels sometimes. But thankfully he never missed taking his pills.

'His schedule was so busy, when he was filming Anger Management in 2012 to 2014 he didn't have much time to himself.

'He'd get done with filming and there would be a girl waiting for him at home. He didn't go out anywhere in the week and stayed at home weekends watching baseball, but he did love to go on vacation.

'While I worked with him he went to Iceland, Scotland, Cabo and Colombia.'

Han said Sheen was taking drugs, including crack cocaine, and drinking heavily throughout that time.

'I tried to keep out of it, yes they were crazy times but Charlie was still a good guy,' he explains.

'Yes there were porn stars, sometimes four at a time, but it wasn't as if Charlie was having sex in front of his staff, he kept that private.

'I used to see him taking drugs in his room and in the party den and he drank Scotch and chain smoked.'

Han says Sheen liked to play music by Slash, the former Guns N Roses guitarist and also a neighbor on the plush Mulholland Estates, but most of all he loved to entertain his guests and make them laugh.

In his professional life the long hours filming Anger Management began to take its toll on Sheen and Han was worried for his health.

'That show was hard on him, he would be in every scene and have to memorize every line. He worked hard,' he said.

'I don't think any one else could have done what he did, pumping out 100 episodes while dealing with HIV.

'As a friend I made Charlie take the pills. He's someone I really cared about, he had done a lot for me so it was only right for me to make sure he was doing the right things to keep himself alive and keep the levels undetectable.'

Han also defends Sheen over his supposed 'meltdown' in 2011 before and after he was fired by CBS from hit show Two and a Half Men.

Show producers justified his firing by painting the actor as a self-destructive, sick addict who was deteriorating mentally and physically.

But Han says Sheen's often bizarre outbursts were scripted, written down in the actor's note book, and uttered to 'get a reaction' and to show his contempt for the show.

The eccentric star even hired a stenographer to take down his thoughts which he wanted to repeat in public or during interviews.

Han said: 'Behind the scenes Charlie wasn't as crazy as people might think, the so called meltdown kind of turned into a huge publicity stunt. 

'He wanted people to take notice, but it backfired in the sense people began to think he was a little crazy.

'But he was fine, he was taking it all in, he wanted to get attention for what he was saying so he was coming out with some crazy stuff.'

Sheen gave a series of interviews during this time in which he coined the term 'winning' - a phrase that has since become synonymous with Sheen's meltdown - and claimed he had 'tiger blood' running through his veins.

Interestingly, Han reveals that Sheen hadn't plucked the famous 'winning' catchphrase out of thin air, in fact he had borrowed it from a baseball star.

The actor said in one interview:

 'The only thing I'm addicted to right now is winning, just winning every second. Winning, anyone? Duh, winning.'

The catchphrase immediately caught on and Sheen began using it regularly, even launching at his own brand of merchandise with the phrase '#winning' emblazoned on baseball caps and t-shirts.

But Han said the superstar actor used the catchphrase he had once heard an unnamed baseball star utter.

In February, 2011, weeks before Sheen's meltdown, several elite baseball players flew on a private jet sent by Sheen and spent the evening at the star's Beverly Hills mansion.

The players were invited to a private screening of Sheen's hit 1989 film Major League.

In the first two movies, Sheen played closer Rick 'Wild Thing' Vaughn.

Han said: 'Charlie invited these baseball stars to his home and they were all sat together watching Major League.

'During the final scenes of the film when Charlie's character Vaughn pulls off an amazing play and one of the players looks over to Charlie and shouts 'winning'.

'Charlie loved it, he's always been a big fan of baseball, he respects the guys who play, and he got a kick out of the phrase.

'Before you knew it he was saying it all the time. Randomly throwing it in to sentences. But no one realized he'd actually borrowed it from a baseball player.'

The other of Sheen's famous phrases 'tiger blood' was influenced from the film Apocalypse Now starring the actor's father Martin Sheen.

In one interview in 2011 he said: 'I have a different constitution. I have a different brain; I have a different heart; I got tiger blood, man.'

In Apocalypse Now there's a scene involving Sheen's dad Martin in which a tiger pounces at two soldiers in the jungle.

Han said: 'Charlie loves that movie and especially that scene. He's very proud of his father for making that movie.

'He said that's where the whole tiger blood came from, he was influenced by that movie.'

Sheen explains as much in Playboy magazine's July/August double issue in 2012, in which he said of his very public 2011 meltdown: 'It wasn't planned, it was just random, The tiger blood? I don't know. It's just a very dangerous animal. And there's a tiger in Apocalypse Now, by the way, so maybe there's a connection there.'

As Sheen's assistant Han was responsible for booking hotels and travel arrangements and running day to day errands for Sheen.

Among the more bizarre duties he had was shopping for an unorthodox sex lube at CVS.

'I would spend more than $200 on dozens of tubes of Aquaphor healing ointment, which is normally used to treat dry skin,' said Han.

'Charlie loved the stuff, he used it as sex lube, the girls would be covered from head to toe in it. I would have to drive some of them home and they'd moan that they'd be all sticky.'

Han said Sheen was extremely generous to those around him and he regularly had to call the star's business manager to arrange wire transfers for large sums of money to girls he had slept with.

'I'd call and get him to wire $20,000 to a girl. And sometimes they didn't even have sex, they just hung out with Charlie. He was very generous with every one, including his staff.'

Sheen also had an elite security team comprised of former Israeli special forces, according to Han.

 

In recent weeks it emerged Sheen set up a control center in his garage where security guards took ID from the girls who visited and made them sign an non-disclosure agreement.

Han, who also signed an NDA but has been given Sheen's blessing to speak out to Daily Mail Online, said he enjoyed his time working with the star and while traveling around with Sheen he was often blown away by his bosses' star power.

He recalls: 'We would be in restaurants or in the street and people would come running over screaming 'Charlie Sheen, Charlie Sheen'. 

'When you get to know someone as I got to know Charlie it's easy to forget they are a big star. 

'He was constantly surrounded by pretty girls wanting their photo with him, when there's a mob waiting outside every restaurant you eat at, you realize you're not in the company of the average Joe.'

'Han, Charlie sheen's former assistant...'

Han said even when they were in a remote part of Cartagena, Colombia in November 2011, Sheen was recognized.

'We were up on a mountain top and there was a guy walking his donkey and he casually mentioned to Charlie, 'hey, that show sucks without you'. That blew me away.

'That's when I realized this guy has some star power, he reaches out to so many people.'

Han says Sheen is 'doing well' since he came out on The Today Show to announce he is HIV positive.

But the star is frustrated by the attacks in the media.

Han said: 'Charlie is doing well, but he's disheartened by the people who are selling him out and by the rumors and half truths being circulated.

'He's got enough to deal with without these constant attacks. He's taking it one step at a time.'
