Christina Aguilera wants her new son to be a rock star.

The 'Dirrty' singer - who gave birth to Max Liron, her first child with husband Jordan Bratman, on January 13 - is playing her baby music from her favourite rock bands.

She said: "Yesterday we had Led Zeppelin blaring through the house! Most new moms play Beethoven, but we're playing Metallica, Bob Marley, and the Rolling Stones!"

Christina, 27, also said Max - who was circumcised in a Bris, a ritual Hebrew ceremony, earlier this month - is already exhibiting some of his mother's most notable traits.

She added: "I'm head-over-heels in love! Max is smiling a lot already, and he has the same little Elvis side smile that I do."

"When Max is breast feeding, I just sit there and stare at him. I'm just in awe of this little miracle."

Christina shows off Max on the cover of this week's People magazine. The issue also includes photos of Max's nursery-rhyme themed nursery, complete with a giant moon and cartoon mural.
