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

I love looking completely different and that my fans won't always know what I'm going to do.

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

'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.

I think confidence is the sexiest thing to have.

We all have our moments of being fed up ... but give me your hand and I'll hold it. If you are being bullied I am thinking of you. You are not alone and it will get better. Don't let them win. It's okay not to be okay.

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.
