Christina Bumps It up a Notch

Christina Aguilera has finally said that she's pregnant -- and celebrated by showing off all her curves last night outside of Koi. Hellooo, mama!

The former dirrty girl proudly put her burgeoning baby bump (and her lovely lady lumps) on display last night as she went to the sushi den with silent hubby Jordan Bratman.

Aguilera even acknowledged the pregnancy to our cameramen -- a TMZ first! -- by saying the couple is "still thinking" about names.
