A new video featuring Justin Bieber has once again caused controversy for the singer as it shows him apparently joking about joining the Ku Klux Klan.

Bieber was 15 when the video was filmed and shows him changing the lyric of his song “One Less Lonely Girl” to say “One Less Lonely N*****” as well inappropriately joking about killing black people.

Justin or any of his representatives have yet to comment on the video or any of its content however a source has spoken to The Sun, who first showed the video.

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

“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.”

Bieber has previously apologised for the contents of the first video, saying: “I'm very sorry. I take my friendships with people of all cultures very seriously and I apologise for offending or hurting anyone with my childish and inexcusable mistake.”
