I am a little crazy but when I'm on-stage, then I really get to play it up and perform and be over the top and it's like an outlet. It's fun to 'wild' out.

I like to go to the movies at The Hollywood Forever Cemetery. They do this thing in The Hollywood Forever Cemetery in Hollywood where everybody sits out on the grass and they project movies and it's very romantic and very old-school Hollywood, so I love that.

I've always felt my spirit animal was a Tiger, so it's funny that now in 'Roar' with Katy Perry - which is a song we write together - there's the line: "I got the eye of the Tiger..." So I feel like there's a little bit of me in there.

When I write for myself, I just get to be myself.

If you can take it to the next level and really tell an interesting story in a unique and fresh way, then I feel like that's a great song.

I think I've learnt a lot about bullying and how to deal with bullying and how to get over that and to just be yourself and forget the haters.

In my head, I wanted to be Madonna, but the music I was writing on paper was not what you'd choreograph dancers in costumes to. It was more coffee-house stuff.
