Justin Bieber rose to superstardom in just a few years after being discovered on YouTube, but the teen heartthrob says he still views himself -- and prefers to remain -- "the underdog."
"It gives me and my fans something to do and to strive for next," Bieber tells NBC News Special Correspondent Ryan Seacrest.

"I feel like, in some ways, I'm -- I am the underdog, Bieber added. "Because it's like there's -- there's people that don't believe like that, you know, I can make the transition from being a teen pop star to -- an adult. So I think that -- yeah, definitely."
During the interview -- which can seen on the Today show and NBC's Rock Center with Brian Williams this Thursday, September 13 -- Bieber also reveals that his next major career goal is to win a Grammy Award.
