Christina Aguilera Expecting A Baby Girl?

Christina Aguilera is expecting a girl with husband Jordan Bratman, according to a new report.

A US publication reports that the singer - who is said to be about 18 weeks pregnant - had an ultrasound at LA's Cedars-Sinai Medical Center on July 25.

According to In Touch Weekly, Christina found out that she?s having a girl and that her due date is December 15.

She has previously told In Style magazine that she wants her kids to be bilingual: ?I definitely want my children to know Spanish, that?s important.

?It?s something that I want to start speaking early on in the house, so I?m brushing up on my Spanish and taking out my lesson tapes on tour.?

Though she is yet to officially announce her pregnancy, the singer has made no attempt to hide her growing baby bump onstage during her Back To Basics tour.

She was recently forced to cancel several Australian shows after falling ill with a virus.
