Baby Max might be getting company!

Only nine months removed from having baby No. 1, Christina Aguilera says she's excited about the possibility of adding to her brood with hubby Jordan Bratman.

"Absolutely, we'll definitely have more kids," Christina tells People magazine. The question is, how many siblings does she plan on giving baby Max?

"I don't know. We'll play it by ear," she says.

The pop singer doesn't plan on putting her red hot career on the back-burner, though.

"I'm in love with my life," she says of her family time. "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 breast feed him and I play with him and then I work. I want to show Max everything about me."
