Christina Aguilera and Her Belly Bump

When is Christina Aguilera going to go public with news of her pregnancy? When the kid enters kindergarten?!

TMZ spotted the platinum blond singer exiting Magnolia restaurant in Hollywood with hubby Jordan Bratman, looking happy and healthy -- was it because she was full, or because there's a baby in that belly?! Or is it a genie in her bottle?!

Either way, Xtina looks fabu.
