Is Jersey Shore star Nicole “Snooki” Polizzi’s new arrival on his way? Looks like it. Today, there have been several reports (including from TMZ) that Snooki checked in to St. Barnabas Hospital in Livingston, NJ, so we’re pretty sure it’s happening.

No official word from the reality star, but she did tweet a photo of a lion, leopard and tiger this evening with the caption “Fierce.”  Yesterday, she wrote, “I’m a balloon waiting to pop.”

Snooki and fiancé Jionni LaValle had been expecting their “mini guido” (Snooki’s words — not ours) in the next few weeks and have already announced they’re naming the baby boy Lorenzo. I, for one, can’t wait to hear how Snooki describes labor.
