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

"I feel like I'm definitely growing up, I mean, I'm 18 ... I think when you're 18, you're not fully a man yet. I think you are becoming the person you're going to be," says Bieber. "But now I feel like I have more responsibilities with different aspects of my life, having to sign more contracts and do more of the business side."

"I just don't wanna be another teen heartthrob because that just annoys me to think that's what people will think of me. I just want to prove people wrong," he continues.

"I think hearing older people say, 'Wow, this new album's great, I didn't know that was Justin Bieber,' or 'As Long as You Love Me', that's Justin Bieber singing?' I like those reactions because I feel like they're judging me on my music and not based on a flick of my hair, because that's not what I want. Although that's funny," he laughs.

And as he looks toward his adult music career, he definitely has his eyes on one particular prize -- "Grammys. I haven't won a Grammy," says Bieber, joking that he's got to work on his acceptance speech because he has struggled in the past at awards shows.

"Just Getting Started" is in bookstores now.
