Tyga has vehemently denied rumors he hooked up with transsexual porn star Mia Isabella— but RadarOnline.com has learned that Kylie Jenner's boyfriend once had a steamy encounter with another trans adult entertainer.
And it was all caught on tape!
While performing at the AVN Awards for adult film stars in January 2013, the rapper, 25, was approached by Delilah "Vaniity" Kotero, 41, a popular transsexual porn actress.
In amateur video taken at the event, Vaniity, in a sequined mini dress, climbs on stage and simulates oral sex on Tyga as he raps his hit "Rack City."
Tyga doesn't seem to mind at all, dancing along as Vaniity grabs his legs and bobs her head near his crotch.
As Radar reported, Tyga denied reports he was hiding a three-year romance with Mia Isabella— but he did admit the private photos of his penis captured in screenshots of an alleged text exchange were real.
According to his lawyer, an unidentified person sent the nude pics to the porn star in an attempt to humiliate him.
Meanwhile, the hip-hop star is sticking with his much younger girlfriend, 17.
As Radar exclusively revealed, the couple is planning to tie the knot when Jenner turns 18 in August.
"They are making plans to quit LA, for a brand new life away from her family," an insider said.
