Kylie has reportedly been sleeping around with another man while also dating Tyga. A rapper named Stitches has revealed details about what happened during his alleged sexual encounter with the reality TV star and also vented out his frustration after being ignored by Kylie.

Stitches, whose real name is Phillip Katsabanis, told In Touch Weekly during an exclusive interview that he had sex with Kylie and also did cocaine with her behind Tyga's back. Stitches claimed the 18-year-old did not even feel remorseful, "not one bit," and never brought up Tyga while they were together.

"I did cocaine with Kylie and then slept with her - while she was in a relationship with Tyga. I had sex with her. We did it all," he said.

The pair reportedly met through a mutual friend, another rapper named InkMonstarr. A simple date between Kylie and Stitches led to another and next thing they know, they were doing drugs and having sex.

"[We did] some drugs. She called me 'Daddy,'" Stitches told In Touch Weekly and added that he has proof that he and Kylie had sex.

Stitches probably meant to keep silent about his tryst with the "Keeping Up With The Kardashians" star if only she had not blocked his calls. After Kylie stopped responding to his calls, the rapper felt it was right to let the media know about Kylie's past. So he did it in the best way he knows how - to rap about it.

The rapper recorded and posted the video called "Kyga She's a Liar" that's supposedly meant to diss Kylie. Stitches reportedly posted the video on Sept. 10 and it has since received over 830 thousand views on YouTube.

The vengeful song contains some rather graphic lyrics that tell of what happened between Stitches and Kylie Jenner's sexual encounter. The video, as seen below, even shows Inkmostarr's text conversations with Kylie and shows the irate rapper talking about Kylie Jenner being a liar.

"I thought it was a good idea to come at her 'cause, I'm not gonna lie - she ignored me after that day we had sex," Stitches further told In Touch Weekly.

The tattooed rapper also mentioned about Tyga's managers having already warned his managers that "if we didn't take the video down it was going to result in violence." However, Stitches told the publication that he will not back down and if Tyga comes after him then he "will stomp him the f**k out."

However, Kylie and Tyga's reps have yet to comment on Stitches' claims. This is not the first time though that the 18-year-old has been involved in sex-related rumors. Ok! Magazine previously claimed that Kylie and Tyga have been offered by adult entertainment company Vivid Entertainment to produce their own sex video in exchange for $10 million.
