Justin Bieber is in hot water yet again after a video emerged of him telling a racist joke and repeating the word “n*****”.

The video, taken around three years ago and revealed by the Sun on Sunday, shows him joking around with friends before asking: “Why are black people afraid of chainsaws?"

One warns: “Don’t even say it, don’t say it,” but Bieber continued regardless, glancing at the camera.

Smiling, he says: “Run n****r, n****r, n****r, n****r, n****r.

“Run n****r, n****r, n****r, n****r, n****r.”

Only one friend seemed to be laughing at the “joke” and the video opened with him being called “mean” after delivering another punchline.

The Sun claimed that Bieber’s entourage attempted to buy the incriminating video themselves to prevent its release.

A source told the newspaper that although the singer had been damaged by several controversies this year, it “tops the lot”.

“Justin has been taken under his wing by some of the best in the industry and they won’t stand by him after this. This will be a real kick in the teeth – showing his true colours on film,” the source said.

It was apparently filmed as part of a documentary, Never Say Never, leading up to a concert in New York in August 2010.

The video emerged after a series of high-profile controversies including photos of Bieber smoking what looked like cannabis, lunging at a photographer, arriving hours late for shows and failing to look after a pet monkey.

Fans were outraged when he appeared to spit on a crowd from a balcony in Toronto, police raided his home after a neighbour’s home was egged and he was arrested in January for drag racing while drunk in Miami.

While Bieber is still supported by millions of dedicated young “Beliebers” around the world, thousands of people in the US decided they have had enough.

A petition to the Government calling for him to be deported has reached almost 274,000 signatures but the White House declined to comment on the demand.

Bieber, rocketed to fame in 2010 with his single Baby, and has since had several platinum-selling albums.

His representatives have not responded to requests for a comment on the video.
