Justin Bieber has revealed that he is getting advice from some of the world's biggest celebrities on how to deal with puberty.

The 'Baby' singing-teen is making sure he is looking after his voice so that he is still able to make the high notes and prepare for when his voice changes.

In an interview with VIBE, he talked about how he's dealing with it: “Everyone’s voice changes. Puberty is a natural thing. I have the best vocal coach in the world and we’re working on my voice and doing what I need to do.

"It’s not like as soon as you hit puberty you stop singing.”

The singer also revealed that his mentor Usher is helping him go through the change from teen sensation to adult star.

Bieber said: “Usher is the best mentor in the world and he survived puberty. He tells me what to do, what not to do.”
