Justin Bieber: 'I rely on Usher'

Justin Bieber has confessed that he asks his mentor Usher for support "all the time".

The 16-year-old singer, who was signed in a joint venture between manager Scooter Braun and the 'OMG' star, explained that he feels comfortable knowing that his A-list confidant is only a phone call away.

"I call him all the time," he told The Early Show. "I ask for advice. We hang out. He's probably the closest person to me in the music business."

It was recently reported that Usher had advised the 'Baby' hitmaker not to date fans.
