Justin Bieber's n-word disgrace: Singer caught on camera making 'racist joke'

Pop singer Justin Bieber has come under fire after a video has emerged of him using the the N-word in a racist joke.

The footage shows the then 15-year-old grinning while using the highly offensive term in an attempt to make his friends laugh.

Justin, now 20, can be heard asking his friends ‘Why are black people afraid of chainsaws?’

 Justin, whose mentor Usher is African American, then started making the noise of the chainsaw  and concluded his ‘joke’ with ‘ Run n*****, n*****, n*****, n*****, n*****.’
