Daddy-to-be Nick Cannon has just revealed via Twitter he's on his way to New York ASAP, because -- it would seem -- he's about to officially become a dad!

Cannon tweeted: “On a plane back to NY. Praying Dem Babies wait for DADDY to come back b4 they pop out! The Cornball Movement don't stop!”

Carey had to leave her own birthday party and head to the hospital over the weekend, because she started having contractions.

The Grammy winning artist recently tweeted: "Comin soon #dembabies! LYMA+thanx 4 making me happy:)"
