Happy Birthday to the Dirrty Girl!

Little Christina Aguilera, who first burst onto the scene with Genie in a Bottle when she was just 18, is now 27 and about to have her own bottle uncorked (ya know, give birth?) any day now!

Xtina and Jordy celebrated Tuesday night with a sedate dinner at Houston's, their favorite spot. Christina must be having some serious cravings for some ribs!
