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!
'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.
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 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.
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 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.
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.
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.
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.
