The news comes on the heels of a sensationalistic National Enquirer cover story which allegedly claims the 50-year-old actor "hid the virus for 4 years" and "spent millions" to cover it up.

Top Hollywood publicist Howard Bragman claims to have been approached by people close to Sheen to deal with the situation and says the actor "is getting treatment, and a lot of people in his life know about it."
"It's been going on for quite awhile," he told People. "He's not necessarily comfortable talking about it. It was very hard to get up the courage for him to talk about it."
While he's battled substance abuse issues in the past and been candid about soliciting prostitutes, Sheen has been married three times.
He was with first wife Donna Peele from 1995 to 1996, then with Denise Richards from 2002 to 2006, and finally with Brooke Mueller from 2008 until 2011.
He was most recently engaged to porn star Brett Rossi.
The former Two and a Half Men star has daughters Sam, 11, and Lola, 10, with Richards, and twin sons Bob and Max, 6, with Mueller. He also has a 30-year-old daughter Cassandra from his relationship with Paula Profit.
Before anyone jumps to conclusions, it should be noted that with the advent of antiretroviral drugs, the average life expectancy of an HIV-positive person in America is not much different than that of an HIV-negative person.
