Pop singer Christina Aguilera has given birth to a son in Los Angeles, her label said on Sunday.

Max Liron Bratman was born on Saturday night. He is the first-born for Aguilera, 27, and music executive Jordan Bratman, 30, who were married two years ago. RCA Records said mother and son were doing well.

Aguilera, a four-time Grammy winner famed for such tunes as "Beautiful" and "Ain't No Other Man," did not confirm growing speculation about her pregnancy until November. She was forced to cancel the last few shows of her "Back to Basics" world tour in Australia and New Zealand in August, blaming the flu.
