Charlie Sheen is HIV-positive and set to reveal his status in a shocking announcement on NBC's "Today" show Tuesday morning.

NBC News announced Monday that Sheen will make a "revealing personal announcement" in an exclusive, live sit-down interview with Matt Lauer, but did not provide further details.

The 50-year-old didn’t just choose to announce his HIV positive status on November 17 to raise awareness. A new report claims that he’s being forced to admit that he has the incurable disease. So what’s making him come clean now?

According to a new report, he didn’t have much of a choice. TMZ says that Charlie confided in a few untrustworthy people, and they spread the word. Once the news reached some of Charlie’s many ex-partners, things got nasty.

Sheen has been safeguarding his HIV status for years while starring on TV, dating a line of adult entertainers and coining catchphrases such as "tiger blood" and "Winning!"

Despite all of Sheen’s precautions, he’s allegedly poised to admit the diagnosis on his own. Perhaps the whirlwind of attention scared him, and made him decide to get ahead of someone else going to the media by telling the people himself.

It's not clear what exactly Sheen will say, but the "Two and a Half Men" and "Anger Management" star has been taking powerful medication since the diagnosis and responded so well that the virus was virtually "undetectable" in follow-up testing, TMZ reported.

Sheen, who in 2011 lost his starring role on Two and a Half Men amidst a notorious public meltdown, has remained largely out of the spotlight after FX decided not to renew his most recent show Anger Management, in late 2014. In his personal life, it was announced in October 2014 that he and adult film star Brett Rossi ended their eight-month engagement.

Regardless of his reasoning, the November 17 Matt Lauer interview is sure to be intense.
