Is Mariah Carey Pregnant?

Does Mariah Carey have something to hide? The typically under dressed star was photographed while vacationing with hubby Nick Cannon in Mexico, and because she's wearing...wait for it!.. layers of clothing, gossip hounds are now abuzz over the possibility that Mimi may be with child.

Note the sports-bra like tank with which Mariah is shielding her cleavage underneath a roomy maxi-dress--to say nothing of the fact that her hand is resting over her stomach! Add that to Mariah's previously expressed desire to have babies with Nick--"I think we would make good parents, and that we'd be able to figure everything out together"--and
you've got yourself one heck of a sorta-substantiated pregnancy rumor.

What do you think, ladies? Are Mariah and Nick expecting? More importantly, did you ever think they'd make it long enough for us to even be asking this question?
