I always prefer to write songs about emotional situations and heartbreak because I like getting into the character.

I'm not afraid to use my personal experiences and put them into a song. I think that's when you get the best stuff anyway, when it's real emotion.

Selena recorded a song I had written and she left my parts in on the middle eight so it ended up being Selena Gomez featuring Pixie Lott.

I long for the old days of Marilyn Monroe and Audrey Hepburn, stars who had real glamour and mystique. We only knew so much about their lives; the rest was a mystery.

I think honesty is a big part. Because when you sing live, you want the audience to believe you.

I think the boy should pay. 'Cuz that's just the way it works on a first-date. But if he doesn't offer, then I will pay... and then just not go out with him again.

The biggest turn-off for me is people who think the world of themselves. Arrogance is not a sexy quality, and it really gets on my nerves.
