Some of the stage outfits I've got are ridiculous. I'll lay out clothes to pack, and it'll look like Polly Pocket clothing - because it's all stretchy, it's tiny. I don't need a case when I tour; I can fit it all in my handbag.

I am a very honest person, and I can only say there are moments in my life where I really did think I was being me in the sense of my morals and beliefs and the way I acted. But when I look back at certain things that I wore and my hair and make-up, I was like, 'Whoa! That wasn't me!' But I didn't know it back then.

As an artist, I try and be controversial, and I have been a bit offensive at times. I have a view on the burka, and I'm sure a few of the Muslim girls and their families would have a view of me on stage in next to nothing!

I think if I wasn't a singer I'd probably do make-up and beauty and hair and something creative like styling; I really enjoy it.

You know, as a woman, it is tough to get to the top - like to get to that respected level in this industry - in any industry, I think.

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

'Just Do It' is exactly what you need to hear when you're in a moment of doubt. When you're struggling, especially with sport... just do it. Stop talking about it, stop complaining about the cellulite, or that you're not able to run fast enough for the bus... just do it.

You should never, ever apologize for anything that makes you happy.

During my stage shows, I am so energetic. It's constant! I just don't stand still. I actually got given a mic stand from my team to say 'Just calm down. Stand still for at least two songs.' But now I just pick it up and walk around with it.

I feel like a lot of the industry and media portray this image of what beautiful is, or how you should dress, or how you should look, and I don't think it's healthy.

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

When I look back, I can see why people thought I was aggressive. My first single, 'Do It Like A Dude,' resulted in a lot of misconceptions about me. I'm confident - but I'm not arrogant.

I'd hate it if everyone in the world liked me, my music and what I wore. It'd make it boring, and I wouldn't have anything to work towards. It's not to everyone's taste, but I can only be me.

I always wanted to be an artist; being a songwriter for myself was always a must but being a songwriter for others has been a bonus.

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.

And I definitely do that very British thing of, take things with a pinch of salt, stiff upper lip, you know what I mean?

Sexuality shouldn't define anyone. It doesn't define me. Love should be at the core of what you do.

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?'

Children used to get bullied at school. Now they go home, and that's where the problem starts - because they sit on their phones all night, thinking about who's 'liked' a photo of them, who hates them, who loves them. They don't know what's real and what's not, editing their lives constantly to fit other people's views.

And that's the kind of thing people think, you know, that if you sign up to be a singer-songwriter you know how to deal with people setting up hate websites, or people being obsessed with you and crying when you touch them, but you don't, and you just have to deal with.

I'm glad I was faced with different cultures when I was growing up because I wasn't fazed by it. It has been a huge benefit to me; I feel comfortable wherever I go.

Do what makes you feel good. Remind yourself of what you're good at and make sure you do that.

I have calmed down my look. Is it really necessary to wear all that jewelry and makeup at 7 A.M.? When you're tired, you start to over-compensate by wearing too much bling.

I have always been the first on the dance floor. Before fame, people thought it made me a good laugh; now, people point and call me an attention seeker! I'm very aware of the way people can view me, but I'm very aware that I have to just enjoy my life.

I've grown up a lot, and I've realized that what I need to make myself happy is the people around you.

I was obsessed with the Spice Girls! I always wanted to be Sporty. Or Posh, but I wasn't pretty enough.

I'm glad I've had to struggle. It's made me the artist I am now.

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.

Whoopie doo guys, yes, I've dated girls and I've dated boys - get over it.

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 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.

My attitude goes back to my childhood. I used to audition for theatrical roles, and you can't stand out in a room full of ambitious eight-year-old girls by acting the wallflower. I realised then that I couldn't do things half-heartedly.

It's really important to me that my niece and nephews can come and see my show, as can my grandad and nan. I love spending time with my family, and music has always bonded us.

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

I think confidence is the sexiest thing to have.

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

I'm someone who'd never base how happy I am on how much money I have, or how good a restaurant is because of how posh it is.

When I was 10 or 11 people started saying there was something special about my voice. But when I was 15 or 16 is when I really thought my hobby could become my career.

I'm so happy people are seeing the eclectic side of me. I'm really honored to be able to push my voice into different sounds. Otherwise it all gets a bit samey same.

The only thing I want to be defined by is my music and personality.

I do my own make-up a lot of the time, and I'm very involved in what I wear.

My style is constantly evolving. Style has been something that I think has been the hardest thing for me to come to terms with.

I might put a nicer pair of heels on and a cooler outfit, but I'm still that naughty girl who likes a slice of cheesecake on my day off.

I like stripper shoes. I like being tall because I'm claustrophobic.

I also surround myself with people who make me laugh. If I'm not laughing, it upsets my day.

Look after yourself; remember that you only consist of your being, so make the best of what you have and look after it. Put good things into your body; eat well.

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