Justin Bieber's mother, Pattie, has revealed that the teen star is planning to "stay pure" until he finds the right girl.

"He's expressed his desire to stay pure, and honour women, and treat women with respect. So hopefully that stays valid," she said during a recent interview.

Bieber himself recently disclosed that he finds it difficult to trust girls, because of his fame. "It's definitely hard to find a girl that really likes me for me. You gotta be careful," he said. 

"Right now, I'm like so busy anyway, so I just have fun, hang out with girls and stuff. Try not to take it too seriously."
