The journey is more important than where you end up.

'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.

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.

But I love singing live. Nothing beats the feeling of going out on stage and going, 'I can really sing.'

I was obsessed with the Spice Girls! I always wanted to be Sporty. Or Posh, but I wasn't pretty enough.

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.

It's okay not to be okay
