After Monday’s revelation that actor Charlie Sheen is HIV-positive, celebrities are reacting to the news. While a report from Radar Online said that Justin Bieber doesn’t want to be in touch with the former “Two and a Half Men” star, actress Heather Locklear expressed support of Sheen in a photo on Instagram. Bieber and Sheen are scheduled to appear on NBC’s “Today” show Tuesday morning with Matt Lauer.

“Justin’s team has requested the dressing room away from Charlie,” a source from the show told Radar Online, adding: “They want to make sure he’s as far away from Charlie as possible.” The report added that singer Bieber was initially supposed to appear on the show before Tuesday but his appearance got cancelled due to the Paris attacks. “Justin wants nothing to do with Charlie,” the source added.

Locklear shared a photo of Sheen and her on Instagram and captioned it: “My heart hurts. Prayers for Charlie and his family.”

Reports said that Sheen got to know about the HIV four years ago and that the amount of virus in his blood is now reportedly undetectable in his blood. Reports also say that he is suspected to have not told many of his sexual partners about him being HIV-positive and that could lead to litigation.

"The interview could open up a lot of sympathy for him, but he has to be concerned about a fear of litigation from former sexual partners," Howard Bragman, a Hollywood publicist and crisis manager, said, according to People magazine, adding: "You don't take that lightly."

The news was first reported by the National Enquirer, which also cited his ex-wife Brooke Mueller as saying: “I had a drug-induced psychotic break at Charlie’s after doing drugs with Charlie for that many days. I couldn’t handle the HIV news. Just six months ago I was diagnosed with the eye disease and then Charlie potentially giving me HIV …” Mueller and Sheen married in 2008 and their divorce was finalized in 2011.

His former girlfriend Bree Olson said Monday that she is being tested for AIDS. “Recorded myself for half an hour being tested for HIV and getting the results. This is so stressful,” Olson tweeted.
