Kendrick Lamar was forced to stop a fan from singing who he'd invited on stage to the stage to help him perform his 2012 track ‘M.A.A.D. City’.
It all went wrong when the fan didn't censor herself from rapping the N-word.
The chick was initially confused as she didn't realise what she'd done wrong.
Aren’t I cool enough for you? What’s up, bro?
Think about what an awesome privilege it would be to jump on stage with Kendrick, but she really screwed up the opportunity.
Kendrick Lamar then explained to her what she'd done wrong:
you got to bleep one single word, though
She then got a second chance to rap along to the track but the crowd wasn't having any of it.
Check out how it all went down in the video below:
