A Kendrick Lamar fan was pulled on stage to join him in a rendition of one of his hits m.a.a.d. City at a show in thee US over the weekend.
While reciting the lyrics, the crowd began to boo as the girl on stage said the N-word amongst the lyrics, which although was the lyrics, was pretty controversial coming from her.
"Wait, wait, wait, wait, wait," said Kendrick.
"Am I not cool enough for you? What's up, bro?" said the fan.
Lamar said someone else - presumably another 'white' fan brought onstage earlier - "knew the rules", before explaining them to Delaney.

The fan then apologised, seeming surprised she had actually said the offensive racial slur, but added that she just wanted to rap it the way it was written.
Lamar then allowed her to give it another go, but many other fans in the audience were less forgiving and yelled abuse at her.
