According to reports, Charlie Sheen will go on the Today show tomorrow to announce he’s been diagnosed with HIV—just one day before a National Enquirer report discussing his sex life is scheduled to drop.

The appearance has been billed as a “revealing personal announcement,” and although NBC has not clarified what that announcement is about, several sites—including TMZ and the Daily Mail—indicate it involves his HIV status.

“Charlie Sheen will reveal to the world that he’s HIV positive. Sources connected to NBC’s ‘Today’ tell TMZ ... Sheen will sit down with Matt Lauer on Tuesday morning to make the announcement,” TMZ reports.

The morning show appearance does seem to be timed to beat a National Enquirer report accusing Sheen of contracting the virus before spreading it to dozens of women in a “multi-million dollar cover-up.”

It’s the culmination of a dogged 18-month investigation that has uncovered how television’s one-time highest paid star potentially spread the devastating virus to dozens of unsuspecting women. Sheen, 50, has already begun a regimen of medication meant to counteract the effects of the disease, sources said.

Neither Sheen’s manager, Jeff Ballard, nor his attorney, Marty Singer, have returned requests for comment.
