Actor Charlie Sheen, who once bragged that he had sex with more than 5,000 partners, will announce on Tuesday’s NBC “Today” show that he is HIV-positive.

Apparently his role on the “Two and a Half Men” sitcom was typecasting to real life.

Sheen's personal life has made headlines, including reports of alcohol and drug abuse and marital problems, as well as allegations of domestic violence. And his feud with “Two and a Half Men” producers went viral in 2011.

Former partners who threatened lawsuits seem to be prodding Sheen – born Carlos Irwin Estevez – into the public announcement. If Charlie’s 5,000 claim is anywhere near the truth, they are going to need a much bigger courtroom.

Besides being Michael J. Fox’s replacement in the “Spin City” sitcom, Sheen was in such movies as “Major League” (1989) and “Eight Men Out” (1988).

Sheen is the youngest son of actor Martin Sheen, who was born Ramón Antonio Gerardo Estevez, and artist Janet Templeton. His paternal grandparents were immigrants from Galicia, on the Iberian Peninsula with Spain and Portugal, and Ireland.

Charlie’s brothers, Emilio and Ramon, and sister, Renée, also are actors.

After his parents moved to Malibu, California, the setting for “Two and a Half Men,” Charlie was a pitcher/shortstop for the Santa Monica High School baseball team.
