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.

Tears don't mean you're losing, everybody's bruising, Just be true to who 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.

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.

Trust Me. Life is not worth living feeling sad and down and lonely. Always be true to who you are.

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 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.
