Well ... a question worth asking!
Her pregnancy was kept a secret although the rumor was very strong ... why not keep her new born baby under warps too?
Christina had a scheduled c-section for the 10th of January, so she might have simply gone and had the baby and we're just not in on it yet!
rumor has it she did give birth but there's no news on when exactly or what gender the baby is.
As usual ... we have to wait for either a pap photo that reveals a clue or an official statement!
UUUHHH! I hate waiting! Don't you?

Update: (1)
reports are circulating that Christina actually gave birth to a baby boy yesterday at Cedars-Sinai ... the same hospital Nicole Richie had her baby girl at.
Digital Spy allege that text messages arrived to close family members saying: "Baby has arrived. Mom and dad are doing well."

Update: (2) after the jump!

It seems the earlier reports of Christina are untrue!
According to a fresh post on UsMagazine, Christina's rep told them that she's not in labor and is still very much pregnant!
Stay tuned for the arrival of his/her royal highness!
