Charlie Sheen HIV Blackmail News: Heather Locklear, Charlie Sheen's co-star on "Spin City," offered her support after the actor confirmed that he was diagnosed with HIV.

The Melrose Place star sent a message of support to Sheen, shortly after the 50-year-old actor confirmed hios HIV-positive status.

"My heart hurts," Locklear wrote on Instagram. "Prayers for Charlie and his family."

Charlie Sheen appeared on "Today" show to reveal that he is HIV-positive.

"I'm here to admit that I am HIV-positive," Sheen said. "And I have to put a stop to this onslaught, this barrage of attacks, sub-truths, and very harmful, mercurial stories that are threatening the health of many others, which couldn't be farther from the truth."

The Enquirer first reported the Sheen was HIV positive on Monday and hadn't alerted his sex partners, including his wives.

"Today" anchor Matt Lauer asked who Sheen informed.

"Enough that I trusted to be in the position and the situation I am today," Sheen answered.

Sheen contended that he told all his sexual partners, including paid escorts.

Sheen also admitted that several people have blackmailed him for their silence and he has paid "enough to bring it into the millions."

"What people forget is that's money they're taking from my children," Sheen said. "They think it's just me, but I have five kids and a granddaughter."

Sheen was open about dating multiple porn stars and his struggles with drug and alcohol addictions. In 1995, Sheen gave a videotaped deposition admitting he had spent $53,000 for "sexual services" from prostitutes over between 1991 and 1993 as part of Hollywood madam Heidi Fleiss's tax-evasion trial.

Charlie Sheen said that it's "impossible" that he has passed the HIV virus to anyone else. The actor admitted to having unprotected sex after the diagnosis, but that the partners were "under the care of my doctor and they were completely warned ahead of time."

"After a battery of tests, spinal taps, all that crap, they walked into the room and said, boom, here's what's going on," he recalled. "It's a hard three letters to absorb. It's a turning point in one's life."

Howard Bragman, top Hollywood publicist and crisis manager, said Sheen has had the disease for some time and has been "getting treatment.'

"It's been going on for quite awhile," Bragman said. "He's not necessarily comfortable talking about it. It was very had to get up the courage for him to talk about it."
