He publicly announced that he was living with HIV in November 2015.

And Charlie Sheen now claims that there are people in Hollywood who are secretly living with the same disease.

'I know who they are, but I will take that to my grave,' the 51-year-old actor told The Kyle & Jackie 'O' Show on Wednesday.

Staying mum: Charlie Sheen claims he knows people in Hollywood who are living with HIV like himself, but will not disclose their names

The former Two & A Half Men star's comment comes after host Jackie 'O' Henderson asked: 'Do you think there are more people in Hollywood that have HIV that wouldn't dare come out and say it like you did?'

Meanwhile, the actor also claims the 'miracle drug' used to treat the virus actually makes him 'safer' than most people when it comes to sex.

'Here's the absolute freaking irony - with the miracle drug that I'm on, this PRO-140, I am actually safer than most cats out there that profess to be on the tallest tree,' he said earlier in the interview.

The Anger Management actor exclusively opened up to Daily Mail Online in December about the clinical trial drug used in his treatment.

Charlie has been involved in a clinical trial for the drug called PRO-140 since early 2016.

As opposed to traditional antiretroviral therapy (ART), which involves taking daily medication, Charlie receives a weekly injection that has no side effects.

In December, he received the news from the head of his clinical trial that he has achieved complete suppression of the virus using this method alone.

Non-existent sex life: The former Anger Management star previously joked that his playboy lifestyle is behind him due to his health woes (pictured with his former porn star ex Brett Rossi)

Since breaking the news of his diagnosis to the world, the outspoken star has been forthcoming about the topic in public.

During his previous appearance on the KIIS FM radio show, Charlie, who once openly bragged about his 'polygamy' lifestyle, admits his sex life is now non-existent due to health woes.

'... Here's the joke these days right, a friend of mine says 'hey man how's your sex life?' and I'm like 'oh it's just f---ing perfect because HIV is such a great pickup line!'' he told the show's hosts.

When asked whether he's still sexually active he replied: 'not anymore' and added that his sex life suffered instantly after his shocking health revelation.
