Justin Bieber doesn't want to be "just another teen heartthrob" and hopes his forthcoming 'Believe' tour will silence his critics.

Justin Bieber doesn't want to be "just another teen heartthrob".

The 18-year-old singer kicks off a gruelling world tour later this month and is determined the shows will take him to the "next level" and silence any of his critics.

He said: "I don't want to be just another teen heartthrob. I know some people are waiting for me to fail, thinking, 'Oh, his time's up.' Well, I like being the underdog, and this tour is my chance to take things to the next level.

"I've never put in more hours preparing, because I want [the tour] to be perfect. I want it to be an event.

"I'm with a personal trainer every day. I'm rehearsing every day. I want people to see this tour and go, 'Wow, that was something I didn't expect.' "

The 'Never Say Never' hitmaker is taking inspiration from the late Michael Jackson in his preparations for the 'Believe' tour.

He added in an interview with USA Today newspaper: "I've been watching videos of his concert tours over and over, he's my inspiration.

"When my team gets together, we're always asking, 'What would Michael do?' "
