Video shows Bieber 'joking about killing black people'

Justin Bieber reportedly joked about killing black people and joining the Ku Klux Klan in a shocking new video.

The 20-year-old pop star - who only just recently apologised after a video emerged of him using a racial slur at the age of 15 - is at the centre of another controversy as new footage sees him alter the lyrics of his 2009 song 'One Less Lonely Girl' by singing, 'One less lonely n*****'.
