Young Thug was put on blast when his now ex-fiancée Jerrika Karlae exposed him for cheating on her. Things got a bit more complicated when the side-chick's identity was added to the mix and now Karlae and the woman in question are going back and forth on social media.

After Karlae posted the receipts of Thug and his side piece, now identified as Amy Luciani, to social media, things got heated as the model did not appreciate her face being put out there.

She's since taken to social media, herself, to let the rapper's former lady know that she's apparently not the one to mess with.

Take a look, below:

In response to Luciani's jabs, Karlae took to Instagram Live to air out her frustrations and she left no stone unturned when dragging her through the mud.

"She ain't even no side b***h," she said while watching Luciani's video. "B***h, you were at the bottom of the totum pole. Come on, bro... B***h, you [look] like a donkey... This a groupie h*e."

Watch her go off, below:

Meanwhile, Thug's responded, himself, to the cheating allegations, posted a picture to Instagram with the caption, "Y cheat when u can creep..."
