Aguilera feels sexier than ever

London Singer Christina Aguilera feels sexier than ever after giving birth to her son Max. "I've grown so much. He's brought out a more playful side of myself. I feel more comfortable in my own skin then I ever have before. I'm more confident - that comes with age. And going through that whole growing cycle of being a mum where with age, I now know exactly what I want and a better understanding of exactly how to get it. And I feel sexier than I ever have also," thesun.co.uk quoted her as saying. Aguilera gave birth to her son in 2008. She was recently criticised by singer Akon for trying to imitate singer Lady Gaga.
