The X Factor' seems to be more about building up personalities and people in tears. And it's not a new idea. The pre-Beatles pop world was full of manufactured pop stars. The thing is that you can't imagine any of the artists you look back at and admire ever going on 'The X Factor.'

It's very nice to be asked to anybody's wedding. Particularly if it's the Prince of Wales. I learned a lot from it, which was to end early and get away.

In the past, my family made a lot of sacrifices. We never got to spend much time together because I was always training. I think now I need to spend as much time as I can with them. This is the life I should have.
