Other sources tell ET the claims that Sheen is HIV positive are true. The 50-year-oldformer Two and a Half Men star is set to make a "personal announcement" in an exclusive interview with the NBC morning program, where he will be live in studio.

Following Sheen's decision to appear on Today, a tabloid report surfaced on Monday claiming that the actor is HIV positive and has known about his diagnosis for the past four years. According to the reports, Sheen has allegedly "made the heartbreaking confession" to multiple individuals, and has already begun a regimen of medication meant to counteract the effects of the disease.

"What I can tell you is that if Charlie is indeed HIV positive and indeed owns it and comes forward, it can be a good moment,” Hollywood publicist Howard Bragman told ET on Tuesday. “I’m sure it’s a very hard personal moment. It takes a lot of courage on his part to talk about it.”

ET has reached out to Sheen for comment. The actor, who is also father to a 30-year-old daughter and 6-year-old twin boys, has not responded.
