When my YouTube videos started to get really big, I was like, 'Man, this is pretty sweet.' It started as my hobby, and then I started traveling and learning how to play different instruments, and then it just kind of became my life.

I do a lot of co-writing with my producer RedOne, and then a lot on my own. I just like to be creative.

Music is my life. I love doing it, so I just do it nonstop all day. And with dancing, I wanted to put on a show for people. I don't want to just be sitting there doing nothing, so that's when I started to dance.

I thought it would be cool to Skype with fans on their birthday and spend, like, a half-hour with them. I did a couple of two-hour Skypes. I just hang out with them and play songs and stuff. At first they're kind of shy, but after a while they open up. I've had a lot of people tell me I'm doing something no one has ever done before.

In L.A., you just kind of come and have a nice hiking-yoga-gym life.

Music is my life - acting's just a hobby.
