Of course Charlie Sheen can't be the only celebrity in Hollywood living with HIV but while he has chosen to go public about having the virus, he said he knows other stars who are privately living with it.

The actor, who has said plenty of outlandish things and been an open book at times in the past, surprisingly did not give the names of those who he claims are also HIV-positive.

His revelation about other celebs that he knows living with the virus came during an interview on the Australian radio program Kyle and Jackie O Show.

When he was 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?” Sheen responded by saying, “I know who they are, but I will take that to my grave."

As we reported, the former Two and a Half Men star announced his HIV diagnosis in November of 2015. He later began taking a drug called PRO-140 that he says has helped suppress the virus.

“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,” Sheen said.
