You need to have a life outside your career.

I tasted huge success with my first album, and when it's happening it feels like a roller coaster you can't get off. You should be very careful about wishing for success on that scale.

My parents are good role models because they've worked hard and gave me a happy childhood.

I can definitely tell when mum has got money because then she likes to go shopping to spend it, whereas dad is steadier and avoids splurges. I like to think I've inherited both sides.

Getting up to dance to your own stuff looks pretty pretentious. And leaving the dancefloor when it comes on is just awkward.

I'm the messiest person I know.

Also, I think women really come into their own in their 30s.
