Friday' is about hanging out with friends, having fun. I felt like it was my personality in that song.

As far as change, anyone from the age of 13 to 19, you become a whole new person because you grow up. There was so much that I didn't know or that I thought I knew because I was just a 13-year-old at the time who thought I knew everything. But I realized very quickly that, no, there's so much about everything that I don't. So what I've at least tried to do is accept that I don't know everything. Life is so much more fun that way. And it's easier. I've just been trying to learn, rather than to pretend that I'm perfect.

Everybody's lookin' forward to the weekend.

I don't really use YouTube that much. I am a very Internet-oriented person, but I'm more of a Twitter freak - I'm always on Twitter. Or chatting with friends.

I grew up being the girl who would always tune in to watch famous people talk about their careers, how they handled scandals and mega fame. I'm trying to pick up tips.

The best thing you can do if you had put something on the internet and watched it spiral out of control is be nice to yourself. Especially when you get on the internet, you have opened yourself up to everybody's opinion, and not everybody's going to be nice. And if you can at least be nice to yourself, that'll help you so much - though it's easier said than done.

Dancing - that's really what I do at parties. I dance and I hang out with friends. That's my partying.
