Miami rapper Stitches dropped a bombshell with the release of his new track "Kyga She's a Liar" featuring InkMonstarr on Friday, Sept. 11, in which both rappers claim to have had sex with "Keeping Up with the Kardashians" star Kylie Jenner, 18.

The diss track and its music video boast about the pair's relations with Jenner and verbally attack fellow rapper and Jenner's boyfriend, Tyga. In the lyrics, Stitches repeatedly shouts, "F*ck that p*ssy ass n*gga named Tyga," and "If she says that he ain't f*cked her, she's a liar." He also goes on to call Jenner a "stupid b*tch," claiming that she "knows the truth" and that he had sex with her, too.

He explicitly describes his alleged sexual encounters with Jenner in the most vulgar way possible: "I done came up on your t*tties and I came on yo' lips, too / And if I want to be honest, it didn't smell that good / But I'm f*cking Tyga's b*tch, so hell yeah this sh*t feels good."

Stitches claims to be the founder of TMI Gang which produces music and released this promotional image for the track "Kyga She's a Liar"

Rapper InkMonstarr, also featured in the music video, claims to have enjoyed sexual relations with Jenner as well and offers this screenshot of Jenner communicating with him on social media as proof:

Although we cannot be sure what sparked the diss track, it seems Stitches is ready to wage war against Tyga. He has shared many Instagram posts in which he attacks Tyga and boasts about his alleged sexual affairs with Jenner.

There is also a rumor Stitches is offering a reward of "up to 50 racks" for anyone who brings him Tyga's gold chain.

Jenner celebrated her 18th birthday on Aug. 10. If Stitches alleges to have had sexual relations with her before then, he's admitting to illegal sex with an underage girl.

Currently, Tyga nor Jenner have responded to Stitches' insults or allegations.

The Miami rapper got his name from the stitches tattooed on both sides of his mouth. His breakout track and music video, "Brick in Yo Face," has accumulated over 8 million views on YouTube. While the song is borderline unlistenable, the video's shock value has made it go viral.
