The footage sees the 20-year-old “star” alter the lyrics of his 2009 song ‘One Less Lonely Girl’ by singing, ‘One less lonely n*****’. 

He then cracks a joke about joining the Ku Klux Klan.

The Sun newspaper released the disturbing video and said it was taken while filming the “Never Say Never” documentary in 2011.

A source said: “Unfortunately this is the devastating reality of how Justin has behaved and reveals his attitude toward such a deeply emotive subject.

“People need to see this. Normal kids in society do not make these kind of jokes. He is protected by a network of staff, but the camera doesn’t lie. This is the real Justin.”

The new racism claim is the latest in a long list of trouble Biebs has landed in lately.

Just a few days ago he was forced to apologise for an earlier video in which he made an inappropriate joke about black people.
