Charlie Sheen will be on the Today show on Tuesday to address HIV reports, ET can confirm.
The 50-year-old actor is set to make a "personal announcement" in an exclusive interview with the NBC morning show, where he will be live in studio.
Following Sheen's decision to appear on the show, a tabloid report surfaced on Monday claiming that the former Two and a Half Menstar has known about his diagnosis for the past four years. According to the tabloid, Sheen "made the heartbreaking confession" to multiple individuals, and has already begun a regimen of medication meant to counteract the effects of the disease.
People also reports that Sheen is HIV positive, according to their sources. "It's been going on for quite a while," Hollywood publicist Howard Bragman tells the magazine. "It was very hard to get up the courage for him to talk about it."
ET has reached out to Sheen for comment. The actor has not confirmed the rumors, and the claims have not been substantiated.
Sheen, a father of five, has made headlines in the past for his reported substance abuse problems. In October, he was headlocked by security and kicked out of Hennessey's Tavern in Dana Point, California, in exclusive video obtained by ET.
