The 16-year-old singer isn’t worried about his voice changing because he has a good vocal coach.

‘Everyone’s voice changes, puberty is a natural thing,’ he said.

‘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.’ he added.
