When I hear him sing and see what he can do, though, it's always a reminder of why I look up to Usher as my mentor and why I will always be an Usher fan to my core. But I'm lucky to say that he's an even better friend to me than he's a mentor. He's truly the real deal.

The Beliebers have done some pretty crazy stuff. Last week, the night before I was due to do a show in Germany, four girls went into a dumpster so they could sneak into the building. They climbed in and hid. When the guys working on the truck started getting the garbage they found them straight away. It was crazy.

My fans are like my glasses. Without them I'd be blurry.

Me plus you. (Imma tell you one time) Me plus you. (Imma tell you one time) Me plus you. (Imma tell you one time) One time. When I met ya girl my heart when knock (knock knock) Now them butterflies in my stomach won't stop (stop stop) Even love is a struggle and it's all we got. So we gun keep keep climbing to the mountain top. 'Cause your world, is my world, and my breath is your breath, and my heart is yours.

My manager is definitely a mentor as well as Usher.

I want my world to be fun.

I'm 19 years old. I think I'm doing a pretty good job...Basically from my heart I really just want to say it really should be about to music. It should be about the craft that I'm making. This is not a gimmick and I'm an artist and I should be taken seriously.
