XXXTENTACION, one of the rap game's fastest-rising figures, is in hot water on social media again for potential ripping on an older song when making "Look At Me."

Over the weekend, he’ was called out by A$AP Mob’s A$AP Lotto for appropriating the sound of his 2015 track "Illness" for "Look At Me," in a series of tweets. "@xxxtentacion u rapping on my beats to get lit u ain’t making waves n****,” tweeted Lotto. “N****s stealing beats I did 2014-2015 to catch waves sit down."

After Lotto called out XXX on Twitter, the volatile rapper reportedly sent him a threatening direct message. It said, "N**** don’t f***in' play wit me," and added "Smh shoulda never ran ya mouth, u gon see me real soon."

XXX's song originally generated attention after he accused Drake of ripping off the song’s flow for "K.M.T.,”" which was released as part of More Life back in February.
