The song is featured on Carey's new Christmas album, "Merry Christmas II You."

Carey reportedly told Radio Disney that she has sung the entire Christmas album to her belly, and then added an offhand statement that has some speculating that she might be carrying more than one baby.

She said, "I just hope that they don't turn out hating Christmas!"

Carey and husband Nick Cannon announced they were expecting last month. The singer said at the time that she's due in the spring.
