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.

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

I'm not afraid to have no make-up on and no hair. I just want to be stripped back.

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.

Sometimes you have to be a diva. All the artists I admire from Madonna to Whitney to Mariah have all been called divas. If you are strong, if you have vision, if you are an artist, you have to do what you believe in. And if you get called a diva for it, then so what.

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

I never complain that I'm tired, because I know as soon as I get a good nine hours' sleep, I'm cool.
