I think the best way to have confidence is not to allow everyone else's insecurities to be your own.

I'm so hard on myself that when I'm in the studio, I'll write 10 songs and only use one. So those nine songs that are left over, I always think, 'Where could these go? Who could they be for?'

I think confidence is the sexiest thing to have.

I'm not really the party person. I don't 'become myself' once I'm drunk. I don't use alcohol to be happy.

I love getting dressed up, but I want to be remembered for my singing.

I used to live in a gap jumper, tracksuit bottoms and a fake flower in my hair. Shocking.

But I love singing live. Nothing beats the feeling of going out on stage and going, 'I can really sing.'

I think everybody has a moment in their career where you have to test whether it was right or wrong. We've all been there. I've looked back at performances of my own, where only you know if it is something you want to repeat. As long as you know when it's not right that you don't repeat it all the time.

I'm an artist, but I'm also a businesswoman, and sometimes you have to play hard.

There are a lot of people holding on to the old Jessie J - whatever that means - but I think there's a lot more people realizing what I'm about. I think people like it.

I never stop working when I'm on stage, and that's my fitness.

When I turned 25, something changed in me. I see children in my future 100%. Soon. I started thinking I want my kids to look back and say, 'Wasn't Mummy amazing?' I've really started thinking about what I'm leaving for them.

I had an amazing childhood and always loved to sing and dance, but there were moments where I had ups and downs with my health that often tested me as it does many people. I've never hidden the fact that my health was sometimes not on my side, but I've never let it define me or deter me from my dreams.

I want young people to know that they can belong - whatever your culture, your religion, your sexuality - that you can live life how you want to live it and feel comfortable how you are.

I have become a bit obsessed with eyebrows. I used to never have any, and then I realised big eyebrows are good, and now I'm an eyebrow fiend. Everyone comes to me to get their eyebrows done.

Songs lay a foundation of who I am going to be forever.

It's weird because when you initially write a song, you write it with no understanding that the world is maybe going to hear it one day. So when you go into the studio, you don't see the hundreds of people at a gig or the viewers on TV, you just write a song without any inhibitions or boundaries.

I've been in dance schools since I was four. I went to the Brit school. I did adverts and plays.

I wasn't always someone who was talented. It was more that I was loud and loved a challenge.
