Charlie Sheen sat down with Matt Lauer on the "Today" show Tuesday to announce he has HIV.
"I'm here to admit that I am, in fact, HIV positive. ... It's a hard three letters to absorb," said Sheen.
Sheen was diagnosed four years ago and said the virus is currently "undetectable" in his blood.
He told Lauer he has spent millions since he was diagnosed to keep people from leaking his condition to the public.
Sheen has mostly been out of the spotlight since his show "Anger Management" was canceled by FX last year.
