You have a tough moment in an early show when one girl, who you went to school with, auditioned. How did you find that?
It was great to see her. I didn't know she had a baby, it's crazy what you can do in a few years after school! I left school eight years ago - I'm so old! So it was nice seeing her. It made me really grateful to be doing what I love. I work really hard, I've worked really hard to get to this point. I think it's crazy how lives can take different directions.
There's been talk about a fix because your backing dancers auditioned. What do you say to that?
I had no clue that they were even going to audition. I'm so happy that they did. For selfish reasons I wasn't, because now I can't have them on tour with me anymore, it was so much fun going on the road with them. I had no idea, but thank goodness they came on the show because they are completely different to what you usually see on X Factor.
Can fans expect to see you perform during the live shows?
Yeah! Even if I have to run up on that stage myself. I'd love to. I hope I get to do the duets with the contestant in the final.
