London, Aug 6 - Pop singer Christina Aguilera has revealed becoming a mother has boosted her sex appeal.

The star gave birth to baby boy Max, her first child with husband Jordan Bratman last January and she admits her partner has given her the confidence to love her post-baby figure and the whole experience of parenthood has made her a much sexier person, reports contactmusic.com.

'Since becoming a mum, I feel I have more knowledge and that makes me feel beautiful. I feel more centred, which makes me feel confident and sexy,' she said.

'The other night, my husband and I were in the bathroom getting ready for bed. I mentioned something on my body that was different before I had the baby. I said, 'That was never like that before!' And he said, 'Are you kidding me? That's what makes you even sexier. The fact that you're a mom and that your body has gone through all those changes, that makes you even sexier,'' she added.
