The twist: he's only 15!

Hi. I'm Rebecca Brayton. Welcome to WatchMojo.com and

today we're speaking to YouTube sensation: Justin Bieber. ("One Time")

So when did you start performing? - Basically, I was always

singing around the house. It was kind of

thing that I just loved to do. I always played a lot of instruments and stuff

so I grew up around music my whole life

Had it always been your plan to pursue music as a career? - No it actually wasn't

("One time" plays)

I was in a singing competition just for fun

And-uh-

my friends and family that couldn't make it. They wanted to be there but they couldn't so I put videos of the competition on YouTube

And-uh-just for them

And it just kind of blew up. I started getting thousands of hits. I started getting millions of hits.

(singing) Oh (unintelligible singing)

Why don't you tell us a bit more about how Usher managed to find you?

Yo, Usher! - JB wassup man?

Basically, it happened after I put the videos on YouTube.

This one manager found me. He flew me out to Atlanta. I was going to the studio and I met Usher... Randomly

And so I ran up to him and said "Usher, I love your songs"

"Do you want me to sing you one?"

And he was like... "Uh...just come up on inside little buddy

I ended up not being able to sing for him. A week later he actually watched my videos on YouTube and then-um-was like

"Man, I gotta get this kid back." So he flew me back to Atlanta where then I got to meet him again and sing for him

So he wanted to sign me but then a week later-uh-Justin Timberlake wanted to sign me

What is it like singing Usher's song for Usher?

It was definitely crazy. If you saw that on YouTube

That was the first time I actually ever sang for him so it was pretty awesome

Rebecca: Now we so many celebrities who became famous at a young age and they kind of trainwreck when they grow up

Uh-how do you plan to stay grounded?

It's crazy. There's a lot of people that have basically trainwrecked as you've said

But I just have so many people surrounding me that are just great people. I plan to just stay grounded and it will be a good road ahead.

Rebecca: Now I am assuming you have girls following you around all over the place now. Was it always that way?

("One Time")

Umm-yeah-(chuckles)-No I just-I had a lot of girls chasing me before this but

Umm...but now there's definitely alot more

("One Time")

Rebecca: Thank you very much

Thank you very much for having me
