Suri Cruise and the Jolie-Pitts better watch out. Beyonce and Jay-Z are having a baby, and he or she already has a Twitter following.

In fact, the fetus has not one, not two, but three popular handles And counting. There's @BeyonceJayFetus ("I AM Baby Fierce "), @BeyJayFetus (I can't keep up with my mentions argh I need a publicist ) and @FetusKnowles (Best believe that Auntie Gwen was already throwing out CRAZY name suggestions ).

It's no surprise that Baby Bey is this popular -- Beyonce pregnancy broke Twitter records by inspiring 8,862 tweets per second after she performed at the 2011 VMAs last week -- but what about these other celeb kids with Twitter personas? Looks like Suri Cruise (of Suri's Burn Book ) and one of Mason Dash Disick's many accounts are worth a follow.
