Sheen reveals he is HIV positive

Charlie Sheen, former star of the hit television comedy "Two and A Half Men," said on yesterday that he was diagnosed HIV positive some four years ago and had been extorted for more than US$10 million to keep the information quiet.

Sheen, 50, told NBC's "Today" TV show he was speaking out because he was being blackmailed, and to refute tabloid reports that he has AIDS and was spreading it to other people.

"I have to put a stop to this onslaught, this barrage of attacks and of subtruths and very harmful and mercurial stories that are about me, that threaten the health of so many others that couldn't be further from the truth," he said.

"I am here to admit that I am in fact HIV positive," Sheen said, adding he was "not entirely sure" how he contracted the immunodeficiency virus.

"It started with what I thought was a series of crushing headaches," he said. "I thought I had a brain tumor. I thought it was over."

Sheen's doctor, Robert Huizenga, also appeared on the "Today" show and said the actor "does not have AIDS."

Sheen, who is three times divorced, played womanizing Charlie Harper on top-rated comedy series "Two and A Half Men" for eight years before being fired in 2011 for bad behavior, including cocaine-fueled partying with porn stars.

At the time, he was the highest paid actor on US television, with a reported salary of some US$1.8 million per episode.

Sheen said yesterday that it was impossible that he had transmitted HIV to anyone since his diagnosis. He said he informed his ex-wives immediately after he was diagnosed.

The actor said he had "always led with condoms and honesty when it came to my condition."

Sheen acknowledged he had paid people "upwards of US$10 million" for their silence about his condition.

"I think I released myself from this prison today," he said.

After being fired from "Two and A Half Men," Sheen set up home with a number of porn stars he called "goddesses" and boasted on YouTube of having "tiger blood" in his veins.

Sheen, the son of "West Wing" TV actor Martin Sheen, said he doesn't feel any stigma from being HIV positive, a condition that affects more than 1.2 million people in the US alone, according to official figures.

HIV, or human immunodeficiency virus, weakens the immune system by destroying cells that fight disease and infection. No effective cure exists, but with proper medical care it can be controlled. If not, one can be infected with AIDS.

"I have a responsibility now to better myself and help a lot of other people ... Others may come forward and say ‘thanks Charlie. Thanks for kicking the door open,'" he said.
