The Snooki & JWoww star celebrated her 7-month-old son Lorenzo's baptism on Sunday and let all of her fans in on the big day via social media.
Polizzi – who recently lost 44 lbs. – showed off her svelte figure in a royal blue floor-length dress. "Proud parents today," she wrote on Instagram, sharing a photo with her fiancé, Jionni LaValle.
In another snapshot of the reality star solo, Polizzi, 25, wrote, "Proud mommy."
Although there were no photos of Lorenzo's actual baptism ceremony, there were plenty from the reception, where the new parents were joined by fellow reality stars Jenni "JWoww" Farley and Roger Matthews.
Farley, 27, played a very important part in Sunday's ceremony – Lorenzo's godmother!
"My precious godbaby," she wrote on Instagram, sharing a photo of a party favor. In another photo where Farley is bottle feeding Lorenzo, she wrote "My love <3."
Polizzi – who says she's already thinking about giving her little meatball a sibling – is taking her mommy duties so seriously, she's working on a book about pregnancy.
