*The Kardashian Jenners are reportedly freaking out right now because a transgender porn star that Kylie Jenner’s boyfriend Tyga was rumored to have cheated with has been linked to Charlie Sheen, who last week revealed that he’s been HIV positive since 2011.

Radar Online reports that Kylie, 18, and her momager Kris are “in meltdown mode.”

“As soon as Kylie’s mom, Kris [Jenner], found out about Tyga’s connection to the same transgender woman that Charlie was involved with, she went ballistic,” a source told In Touch. “For obvious reasons, Kris insisted that Kylie get to the bottom of this potentially life-threatening mess. So Kylie went straight to Tyga and confronted him.”

“Tyga denied he and Isabella were ever an item,” revealed a Kardashian family source — even though, as RadarOnline.com reported, the two were rumored to be involved in a three-year affair.

“We continued in our friendship until it did become romantic and we dated steadily for a few years,” Isabella revealed last summer.

Now, Kylie’s “a total wreck,” noted the source.
