Nicole "Snooki" Polizzi will soon have three meatballs munchkins to call her own!

The Jersey Shore star -- who is mom to son Lorenzo and daughter Giovanna with husband Jionni LaValle -- is expecting her third child, she happily shared on Instagram.

"What I’m thankful for this Thanksgiving," Nicole captioned the heartwarming photos above, featuring her two kiddos preciously holding a sonogram of their baby brother or sister. The second snap is rather priceless: Lorenzo is grinning from ear to ear, but Sissy has other feelings.

Offer your special congrats to Nicole, Jionni, Lorenzo and Giovanna in the comments and stay with MTV News for all baby updates! And be sure to keep watching Jersey Shore: Family Vacation every Thursday at 8/7c.
