Now that she's a mommy, Christina Aguilera doesn't get nearly as many chances to go clubbing - but last night, everything fell into place for the Dirrty girl!

Xtina and her hubby Jordan Bratman partied like a couple of rockstars at Villa last night with a few mutual friends. Looks like Christina had a whale of a good time - heck, as Jordan was driving away, the usually-stone-faced starlet even waved at the paps and flashed them a smile!
