People like hearing songs that sound like something they've heard before, that's reminiscent of their childhood and of what their parents listened to.

In my mind, I imagined L.A. to be skyscrapers on the beach. Of course, that's not what it actually looks like. And growing up watching 'Beverly Hills 90210' and 'Melrose Place,' I always had an obsession with L.A. and California in general.

One thing I'd tell an up-and-coming singer is to never rely on other people for anything. The more self-sufficient you can be, the better off you'll be.

I have a notebook of concepts. There are titles everywhere if you are looking for them. I pull from them. There is a secret list that I keep for myself about what I want to sing about, and those are the ones I know I am not going to give up for someone else.

When my parents were like, 'We're going to the Northwest,' I thought, 'You've gotta be kidding me.' I was so depressed. The cold weather really did not agree with me. When I moved back down to L.A. at 16, I felt like it was home - it was where I belonged.

When I'm dealing with Britney Spears and Katy Perry, these massive brands, like, really, very Coca-Cola, you know what I mean? There are certain kinds of standards. There are risks you can take, and there's risks that you don't. And I think I'm interested in taking a little more risk in my own music.

When I moved to Seattle in fourth grade, I joined the Seattle Girls' Choir. It's a world-class choir, and we competed, toured Europe, and went and sang at the Vatican, so it was a really awesome experience to have that young.

I started writing my own songs from the time I was a little kid. I would write my own lyrics to other people's songs that I heard on the radio and take whatever song and make it about fairies and angels - whatever little girls sing about.

I like to think of myself as the people's pop star a little bit. I respect Lady Gaga so much, and I love what she does, but she has this kind of mysterious, out-of-reach thing. I'm just not that - as much as I'd love to have that sort of mystique, I think I'm kind of an open book.

I've been singing since I could talk, pretty much. My dad was really musical and taught me how to sing harmonies and got me a karaoke machine with tape decks.

I saw Tina Turner do 'Proud Mary' on TV, and it was so electrifying and such a unique experience. I remember crying out of excitement, and I knew that I wanted to be a performer and make people feel excited and moved, and that's why I gravitated towards it.

If I know I will be working with someone and they are not keen with writing with a girl, I like to be non-threatening and cool so they will trust me. It's a thought process of who work and how I want to present myself.

I think what it means to be an 'American Girl,' and what I wrote the song about, is our freedoms. The idea that we as Americans can be what we want to be and say what we want to say and that we take it for granted.

'Teenage Dream' was the most difficult song I've ever been a part of. We wrote five different versions of it. We couldn't get the lyrics right. Max Martin and Dr. Luke wrote most of the melody, and then Katy Perry and I were responsible for getting the lyrics right.
