London, (ANI): R&B star Usher has urged teenage pop sensation
Justin Bieber to make sure his voice doesn't change too much as he
grows into a man. The Yeah! hitmaker has been mentoring the
16-year-old since they met in 2008.
And now, Usher has warned the teenager to look after himself.
"We're taking the right steps to make sure that he didn't lose too
much (ability to hit high notes). It's all about what you eat and
really just taking care of yourself," the Daily Star quoted Usher
as telling Access Hollywood.
