Actor Charlie Sheen is expected to discuss the rumor that he is HIV-positive on the "Today" show on Tuesday, according to a report by TMZ.
TMZ also reports that Sheen has known he has the disease for "more than a year" and has been keeping the news under wraps.
TMZ also reports that Sheen has been taking medication for close to two years, and that the virus is now "undetectable" in his system.
Howard Bragman, a Hollywood publicist, told People Magazine that he's "known about this a long time, it's not a surprise to me."
"It's been going on for quite awhile. He's not necessarily comfortable talking about it. It was very hard to get up the courage for him to talk about it," he said.
Sheen is 50 years old and is the son of actor Martin Sheen. He appeared on the TV sitcom "Two and a Half Men" from 2003-2011 before a highly publicized feud with CBS led to his dismal from the show. Among the network's complaints was Sheen's erratic behavior on set and his drug use.
Sheen most recently had a small guest appearance on "The Goldbergs."
