Aguilera: 'I definitely want more kids'

Christina Aguilera has said that she is already thinking about expanding her family.

The popstar, who gave birth to son Max in January, claimed she would "definitely" have more children with husband Jordan Bratman in the future.

"How many? I don't know. We'll play it by ear," she told People.

Aguilera, 27, also admitted that she is finding it hard to separate her roles as a mother and a performer.

She said: "I'm in love with my life. But Mama has to work, Mama has to do a job.

"I think it's important to share what I love - what makes me me - with my son. So. I change diapers and I breastfeed him and I play with him and then I work.

"I want to show Max everything about me."
