You always have guilt as a working mum, and you overcompensate by buying them loads of things. That was what I was doing, anyway. I've kind of realised now that I'm the best mum that I can be.
After 'X Factor,' I got loads of gigs. Then I went on holiday just after the tour and bought my Rolex in Tenerife. I needed to go through that phase - splurge and see that it's worthless - to get it out of my system.
