Christina Aguilera doesn't want a "normal" child.

The 'Not Myself Tonight' singer - who has a two-year-old son Max with husband Jordan Bratman - is delighted with the toddler's progress, but is hoping he grows up to be as unconventional as she is.

She said: "Oh he's normal, trust me. He is a little rambunctious firecracker of a two-year-old boy.

"But I don't know if I want a normal child. What is 'normal' anyway? Who even knows? I don't want that - I'm not normal."

Christina - who is set to make her movie debut opposite Cher in 'Burlesque' - has previously admitted she and her music executive spouse enjoy "naked Sundays" at home, but now says motherhood leaves her too busy for the tradition, though the couple still make time for racy fun.

She added in an interview on UK TV show 'GMTV': "We have naked moments - I wouldn't call them Sundays as I've been working so much on my movie, but yeah there's definitely time for fun and play in my day."

The 29-year-old beauty also admitted she "feels sexier than ever" since becoming a mother.

She explained: "I feel sexier than ever. He's brought out a more playful side of me, I'm more confident. It's like a coming of age - experiencing the growing cycle of being a mom."
