Confidence is key. Sometimes, you need to look like you're confident even when you're not.

My mum and I do cardio kickboxing classes together.

Touring is tough. You're almost in a haze because you don't really know where you are half the time: You're in a hotel room one moment, and the next thing you know, you're onstage performing for 60,000 people, then you're back on an airplane. It's very hectic and I couldn't do it without my family.

I love being in the studio and singing on stage and performing. It's so much fun. I love every second of it - and I love the way you get to show who you are. I love the way fans are really passionate around the world, so I adore performing and hearing people sing along in different countries.

If you have paparazzi, you know you've gotten somewhere.

The sweetest thing a guy said is that I look pretty with or without makeup.

My style is boho chic. I love that time period - the patterns, the prints, the people, the music, the vibe.
