Doing our best to ignore Christina Aguilera's enormous boobs in the photo below, we'll just concentrate on how nice it is to see the singer back in the public eye.

The Dirrrty one made her first appearance following the birth of son Max Bratman. Signing autographs of her new DVD, Back to Basics - Live and Down Under, Christina talked about the young one's recent bris:

"It was really interesting because I'm not Jewish, but my husband is. I never really knew a lot of Jewish people growing up, I never knew about a bris. It's all a learning process. Of course, we're such a non-conventional couple that we had penis balloons everywhere."
