CHRISTINA Aguilera is keen to have more kids – just not yet.

"I definitely want to expand our family eventually but, for now, Mummy's going to work – Mummy's got to do mummy stuff now," she tells Entertainment Tonight.

The 27-year-old singer gave birth to her first child Max, with husband Jordan Bratman, back in January.

"(Max is) amazing, incredible," says Christina.

"He just lights up my whole world every day with his laughs and his smiles. He's cutting teeth now and he's just amazing."

Christina was speaking during a promotion of her new perfume Inspire.
