Pop star Justin Bieber says he almost turned his back on his music career after people started to view him as a reality TV star due to his wild behaviour.

The `What Do You Mean?` hitmaker, who walked away with five gongs at the MTV EMAs last week - has revealed there was a point over the past three years when he was spiralling out of control when he toyed with throwing it all in, reports femalefirst.co.uk.

"For a minute, I was jus too in my head, and I just wanted to quit everything. But I knew that was the easy way out. I know I'm meant for this.

"I know God has a greater purpose for me to be in this position. It's just up to me to take that calling and respect it. It takes integrity to last in this business,` he said.

The 21-year-old, who has had a number of run-ins with the law since his rise to fame, believes his wild behaviour blocked people's vision and stopped them from seeing him as a musician and, instead, encouraged them to think of him as a reality TV star.

"I was almost like a reality star, rather than a musician. So I was just giving them ammo and they were feeding into it and I was feeding into it, and I wasn't caring. I was just like... being a jerk, a little bit,` he said.
