Christina Aguilera‘s Back to Basic’s Tour took her to Tokyo last night, where the blond bombshell wowed a packed crowd.
Page Six wonders, however, if Aguilera’s womb’s packed, too:

Rumors that Christina Aguilera is expecting a baby “are definitely true,” according to a well-placed Page Six source. “She’s been telling friends,” said one snitch, who revealed, “she has to be three months now, because she’s announcing it.” This would be the first for Aguilera and her husband, Jordan Bratman.

We’re all about Ms. Aguilera reproducing, just as long as the little urchins don’t derail her career.
