I can't watch my first audition because it makes me too upset. I just think it is really sad. I look at myself and don't recognize myself. I do think fame and fortune changes people.
I've just grown as a person, accepting my flaws as well. Before I was very insecure and I used to just hide, and now I just accept that I'm an imperfect human.
Sometimes I won't put a lot of make up on; I won't put foundation on. I'll just pop a bit of blusher on. I'm not obsessed with trying to look like a Victoria's Secret model - it's real life.
I remember sitting on a bench in New York and sobbing and realising that my ambition to be a singer was making me selfish - I was a mother with two children, and I needed a backup plan.
I knew I could sing. That one thing I did believe in was that I could sing, but then constantly getting rejected, it started to get me down. But my voice was always there and my dream and my ambition was always there when I went through bad times.
I am lucky in that I love what I do, but it can still be hard to be away from the kids for long lengths of time. At the end of the day, all I want is to be with my kids, but it's worth it to create a future for my family.
I think being a mum gives you extra qualities. I'm more feisty, fiercely protective and less selfish. The main trait I want to instill in my kids is kindness. I think it's the most important thing. If you're kind, you'll go a long way.
The aim for me is to have a long career. I've got a couple of kids, and so I can't really be a fashion because I have to sustain a life for my children.
I took lessons since I was little; I used to pay for my own singing lessons and take myself. Just take the bus when I was a kid and go. But I'd been writing music for years, since the smallest age.
Growing up, we didn't have anything. My mum wasn't well, so I was in three care homes then foster homes before me and my little brother went back to her. I was passed from pillar to post.
You have to be really strong in the music industry, and I'm naturally very timid. That was really hard for me. You have to be tough. You have to make decisions and be a businesswoman.
Constantly having to think about money is not nice. People used to say, 'Being rich doesn't make you happy'. And I'd think, 'I've got no electricity, nothing - tell that to my empty fridge'.
When I was on the X-Factor, I found that I grew a lot as a performer. I knew I could sing but I didn't believe in myself enough... I needed to hear that I was good.
