Welcome to Bumpwatch, Mariah Carey

Singer's abrupt, unexplained departure from forthcoming film fuels speculation she's pregnant; rep refuses to comment

Attention, female stars of reproductive age who unexpectedly and inexplicably drop out of upcoming projects: the baby-bump watchers will come for you.

That's exactly what's happened to Mariah Carey, who abruptly pulled out of a role in an upcoming Tyler Perry film without so much as a cursory statement blaming scheduling conflicts, creative differences or another vague catch-all excuse.

So, what's the conspiracy-happy public to think? Well, that she's packing, of course. Specifically, in the midsection.

The 41-year-old superstar hasn't confirmed or denied the rumors—though the pictures of her and hubby Nick Cannon leaving a medical building earlier this month certainly haven't helped curb speculation.

And neither has her departure from For Colored Girls Who Have Considered Suicide When the Rainbow Is Enuf. Ditto her rep's no-comment comment on the, um, growing situation.

"I'm not at liberty to discuss her personal life at this time," Carey's spokeswoman Cindi Berger said.

But we won't have to wait long for an answer. Cannon, who is the midst of a weeklong stint on E!'s Daily 10, promises to give us the exclusive scoop later today and you will not want to miss out.

Either way, let us be the first to say: if it's true, congrats! If not, well, at least she's in good baby-bump-refuting company.
