Rap star Tyga is conceding that recently released photos of him exposing his penis are authentic, but his attorneys insist they were sent from someone as part of a conspiracy designed to "maliciously shame him."

Attorney Lee Hutton told TMZ the person who actually sent them not only betrayed the rap star, but also used them to "manufacture a fake story."

That's in complete contrast to what well-known transgender porn star Mia Isabella told HollywoodLife when she alleged that the two have been hooking up for the past three years and their relationship overlaps the time he's been with current girlfriend Kylie Jenner.

In addition, texts allegedly exchanged between Tyga and Isabella were sent to several media outlets as proof of their involvement.

"[Tyga and Mia] had an ongoing relationship for almost three years since she moved to LA," a source told HollywoodLife. "She's down for him has been since he was with Chyna."

In one text message allegedly exchanged between Tyga and Isabella, the two discuss what they would do if news of their involvement ever got out. Ultimately, Isabella vowed she would claim she worked on his clothing line.

"If any haters try to publicly connect us I'll only ever say we were friends through fashion because of my work as a stylist and your clothing line, never sexual." Isabella adds, "Cuz [sic] that h*e who used to be my roommate been running her mouth and that b*tch we did a 3 some with last summer in weho [sic] who used to be my friend."

Tyga then allegedly responds, "Ok, don't trip. That's why we gotta be low key, can't trust no one."

Sources close to Jenner told HollywoodLife she plans to stand by her man.
