Justin Bieber has revealed uncertainty over his own heritage, saying that he is either part indian or part inuit - he isn't quite sure.

In his current Rolling Stone interview, the singer speaks of his pride for his heritage, and even though he is uncertain of his true bloodline, he is certain he is entitled to free petrol in his Candian homeland.

"I'm actually part Indian," he says in the interview. "I think Inuit or something? I'm enough per cent that in Canada I can get free gas."

Bieber previously admitted that his birth was 'an accident'. Speaking to Australian radio station 2Day.FM, he said: ""I was definitely an accident, [but] it's great my mum is super young.

"She's a friend and a mum. She's always been really strict, she still keeps me in line."
