she was tested and got the all clear

She fears he may have infected dozens of women

A 27-year-old porn star, who had sex with the unnamed actor, spoke to Daily Mail Online

A porn star who had sex with the Hollywood superstar believed to be secretly battling HIV has told how she fears the actor may spiral out of control as he struggles to come to terms with the devastating diagnosis.

The adult actress believes the playboy may have infected dozens of women - and is worried he could turn to drugs to overcome the immense guilt.

She claims the lothario has slept with at least 50 porn stars over the past few years and fears the porn industry could face a 'HIV epidemic' as a result.

In an exclusive interview with Daily Mail Online, the 27-year-old, who we are not naming and was recently tested herself and received the all-clear, told how four successful porn stars who had sex with the actor in recent years have disappeared from the porn film business – and she fears this may be because they contracted HIV.

She also revealed how the Hollywood star - whose identity is not being revealed - has been regularly sleeping with transsexuals - as well as porn actresses.

The blonde, who ended up pregnant by the unnamed superstar, met him at a drug-fueled party in 2011. She was one of five porn stars at the party.

Once the other women left, she went to his bedroom to have protected sex - but the contraception failed.

Knowing how promiscuous the star was, she feared she may have contracted something and got tested straight away - but was given the all-clear.

'We just had regular sex but there was a condom slip - that's the reason I got pregnant,' the woman, said.

'I was pregnant and then had an abortion so obviously his DNA was in me but that was almost five years ago.

'I've been tested lots and shooting porn since then but I'm still going to get retested.

'I've had plenty of tests in the past few years so I have no worries that I have contracted something but I do worry for the girls I do know.

'There's a lot of girls that I know personally - that have been seeing him over the past two years.

'The funny thing is there's four girls that have been seeing him that have stopped shooting porn recently.

'I think they might have contracted HIV but obviously I'm not going to go and ask them and they would never admit it - it's not something you want to tell people.'

The porn actress said the news of the diagnosis has sent shockwaves across the adult industry.

The rumor was reported in The Sun which claimed the actor's list of exes includes an award-winning actress, a religious movie star, a top Hollywood personality with a controversial past, a TV star, a media personality and a model.

A similar article appeared in Radar Online, which claimed the star is preparing for legal action by women who say he put them at risk.

And the internet has exploded with rumor and gossip about the identity of the infected actor.

The porn star told how she is particularly nervous about shooting her next porn film next week in case she has to shoot scenes with an actress who may have slept with the star.

'I know lots of girls who are worried right now that they might have contracted it,' she said.

'And the thing is I'm now nervous because I have shot in the last couple of months so think about it - if he's been seeing porn girls in the past couple of months and they're shooting right now it could start an epidemic in this industry.

'I have a shoot on Monday I'm really nervous now because I'm going to be shooting with girls who might have seen him in this time, girls that I don't know.'

'I would guess he has slept with about 50 porn stars or less over the past few years – only because I know he has a lot of repeats.

'He is bisexual too - he would pay girls to bring him transsexuals to have sex with.

'He'd have a girl bring three at a time because if he didn't like them he wanted to have a choice.'

The actress says she wasn't surprised when she heard the actor had contracted HIV.

'It's not shocking to me but it's scary because now I'm nervous to shoot,' she said, adding that it's now 'common knowledge' in the porn industry that the star has tested HIV positive - and may have even had the virus for the past two years.

She is now worried how the actor will cope with the devastating diagnosis and fears it could send him over the edge.

'From what I know of him personally he was the kindest, most giving person but he can also be crazy.

'I think this will send him on a downward spiral because of the fact he needs his girls.

'He wants his people, he wants to keep hiring us but who will want to have sex with him now?

'But for most girls no way.'

'The actress said she believes the star would have used protection with the women he has slept with - whether or not he knew he was HIV positive - but she couldn't know for sure.

And she is worried that other women may have had a contraception malfunction like she did.

The porn actress said she wasn't sure how the famous actor would deal with the public interest in his diagnosis - and also the repercussion from anybody he may have infected.

'I think he might deny it all the way, but at some point it's going to be public record.

'I think if any girls have contracted it they're going to sue him.

'I mean how angry would you be – him withholding that information from you? I'm really interested to see if a girl will come forward.

he porn actress said she wasn't sure how the famous actor would deal with the public interest in his diagnosis - and also the repercussion from anybody he may have infected.

'I'm sure he'd be very remorseful because he is kind and I'm sure he'd feel very guilty and I'm sure he'll be very human-like in his response. But I don't know.

'I hope that maybe he can team up with Magic Johnson and start doing charity things and embracing it and get treated for it and be healthy. And also change his lifestyle a bit.

'He's either going to do something like that or he's going to spiral down.'

Anyone who has unprotected sex is at risk of contracting the HIV virus, which weakens the immune system and can develop into deadly Aids.

It is spread through the bodily fluids of infected people through unprotected sex, breastfeeding and sharing needles.

Major strides have been made in the past 30 years in fighting both HIV and Aids.

There is still a major stigma around both, with many wrongly believing HIV and Aids affects only gay men and drug users.
