In the wake of Charlie Sheen's big announcement, Kylie Jenner is panicking overthe possibility thatboyfriend Tygamay haveHIV. After the American actorannounced last week that he wasdiagnosed HIV-Positive four years ago, scores of people from Sheen's past expressed worries over their own health, and not just people who have been sexually involved with him, but also many who have had indirect contact.

Tyga may have slept with same girl as Charlie Sheen

The 18-year-old socialite has enjoyed a loving relationship with rapper Tyga for about a year now, and the 26-year-old singer might have had, in the recent past, an affair with Mia Isabella, a transgender porn star who has also been linked to Charlie Sheen.

According to a source who spoke to In Touch, Kris Jenner panicked when she learned about all these relationships and fearsthat her youngest daughter has already been infected. Thismay have been the reason why Kylie and Tyga broke-up for a few dayslast week. "For obvious reasons, Kris insisted that Kylie gets to the bottom of this potentially life-threatening mess. So Kylie went straight to Tyga and confronted him," an insider told In Touch.

The fears of Kylie and mother Kris areunderstandable, despite Tyga's denial of having had a relationship with Mia Isabella. The affair was allegedby the porn actress who claims to have been in a secret relationship with Tyga since early 2013.

Charlie Sheen confirmed he is HIV-Positive

Kylie's worries began with Sheen's announcement. "I am here to admit that I am HIV positive," revealed the 60-year-old actor during NBC's Today show, last week. He also said he was diagnosed with this illness four years ago and he chose to confirm it because he was being blackmailed.

The Two And A Half Men star said he told some of his friends about his illness, looking for some kind of help and support, but thatsome people whom he trusted tried to cash in on their knowledge.

Reportedly, the Hollywood star had unprotected sex with transgender Mia Isabella, what she didn't deny. However, the 30-year-old actress says that her own HIV test came back negative.
