Justin Bieber has revealed that he does not allow fame to get into his head. The Baby singer talked about his tough childhood and how it helps him remain humble.

"I remember being poor and being teased by other kids," he said. "I remember sitting in restaurants with my mother and she'd make me order water instead of soda.

"I remember so badly wanting to order a soda. And I also remember that when I got my first big pay cheque I was so glad to be able to use that money to take care of my mother," the 21-year-old stated.

The Sorry singer further explained, "I'd like people to understand that when you have so much on and you're constantly under scrutiny, it's a very tough place to be. It was a hard time for me and I needed to rebel against everything.

"That's when I started making a lot of mistakes. When you're 19 or 20, you're going to make a lot of mistakes - it's just that I have cameras following me everywhere."

Meanwhile, in an interview with Billboard, he had talked about his strained relationship with his mother, Pattie Mallette. He claimed: "It was pretty non-existing. I was distant because I was ashamed. I never wanted my mom to be disappointed in me and I knew she was. We spent some time not talking, so it takes time to rebuild that trust. She's living in Hawaii now, so it's hard, but getting better. She's an amazing woman and I love her."
