Charlie Sheen is scheduled to appear on NBC's Today show where he is expected to announce that he is HIV positive, TMZ reports.

NBC News announced Monday that Sheen is scheduled to be interviewed by Matt Lauer and will make a "revealing personal announcement", but no further details were provided.

Sheen was fired by Warner Bros., producers of his hit series Two and a Half Men after a very public meltdown in 2011, and hasn't been heard from much since the cancellation of his most recent series, FX's Anger Management, in 2014.
