*Mariah Carey may have slipped up and revealed that she is pregnant with more than one baby.

While promoting her new CD “Merry Christmas II You,” the mom-to-be, who is expecting with husband Nick Cannon, was talking about how she sings songs from her new album to her baby bump when she referred to the fetus as “they.”

In an interview that aired today with Radio Disney’s Ernie D., Mariah joked, “I just hope that they don’t turn out hating Christmas!”

No word if it was a Freudian slip or an innocent slip of the tongue.
