Is Mariah Carey Expecting Twins or More?

Are there two—or more mini-Mariah Careys on the way?
The 40-year-old singer, who recently announced that she and husband Nick Cannon are expecting, spoke with Radio Disney’s Ernie D. to promote her new holiday CD, Merry Christmas II You, and while explaining that she sings songs from her new album to her baby bump, Carey let slip wit an offhand statement that will no doubt launch 1,000 rumors: “I just hope that they don’t turn out hating Christmas!”
The word THEY is Very interesting.
What do you think? Are there multiple mini-Mimis en route?
