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 Men star 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.
