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

Life isn't about winning it's about what you learn and how much you can grow.

A hairdresser who did my hair said, "You, my darling, have something that we call successful' hair," which is basically battered hair that's split and falling out in the back because you've had to blow-dry it every day. I don't want my hair falling out, so I wear wigs!

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.

However old you are, however much you love life, however happy you are, how healthy you are, it doesn’t matter. Nothing’s guaranteed. And I think it made me want to take that risk to expose myself as me and not as a version of myself. I don’t become Jessie J. 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.

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'd love to have a fashion range; I've been dressed by the amazing Vivienne Westwood, and fashion is something I'm a huge fan of.
