XXXTentacion got the shock of his life when he was knocked out during a performance on Wednesday night in San Diego.
The rapper was performing on stage when an unidentified man appeared on the stage, and sucker punched him.
The attacker then proceeded to get on top of XXX as he lay unconscious on the stage. Security was quick to swoop in to pull the attacker off.
The 19-year-old rapper was carried off stage and allegedly remained unconscious for two minutes while a brawl ensued on the stage.
That's not the worst of it, however.
After all of that went down on stage, someone was actually stabbed backstage. The odd thing about all of the random events was that the fans were chanting Rob Stone's name.
Stone is another rapper from San Diego, who apparently hates XXX. It's such a horrible thing to happen during a show, but XXX took to Twitter following the attack to blame the venue and security for stitching him up.
According to TMZ, no arrests have been made yet, and the cops want to speak with XXX for a statement. Will he want to chat to the police about it?
Something tells us he will if he wants to sue the venue and security for stitching him up.
The rapper, born Jahseh Dwayne Onfroy, rose to fame when his song, "Look at Me" managed to chart at number 34 on the U.S. Billboard Hot 100.
The story is still very much developing, and we'll keep you updated on any new developments.
