Christina baby watch is on

Word on the street is that Christina Aguilera is already at Cedars awaiting a very special delivery—and we’re not talking ’bout the Domino’s kind. She has allegedly been there since last night, but when Planet Gossip’s Marc Malkin checked in this morning, her rep said there was nothing to announce…yet.

But will Nicole Richie beat her to the punch? She’s also expected to give birth at Cedars any day now. (For publicity’s sake, we hope the ladies are at least a couple of days apart!)

Stay tuned for all the happy news!
