Vocal coach helping Justin Bieber get through voice breaking?

Justin Bieber reportedly has a vocal coach with him at all times, to help him get through his voice breaking.

The 16-year-old singer is struggling with the affect puberty is having on his vocal chords, but he has a vocal expert coaching him to make sure he can still perform.

“Justin is physically developing at a slower rate than most guys so his voice is only breaking now,” a source said, reports ShowbizSpy.

“He’s working with the best in the business, a specialist called Jan Smith, to make sure he gets as much vocal rest as humanly possible for a working pop star.”

“It’s the same people who worked with Usher when his voice broke.”

Justin has previously insisted that puberty is not a problem for him.

“Everyone’s voice changes, puberty is a natural thing,” he said in July this year.

“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.”
