Snooki and her fiance Jionni LaValle baptized their 7-month-old son Lorenzo on Sunday, and the reality TV star tweeted all about the special day.
Dressed in a floor length royal blue gown and white heels, the former "Jersey Shore" star posed alongside LaValle before setting out for the church.
"Proud parents today," Snooki, whose real name is Nicole Polizzi, tweeted to her 6 million followers.
The couple, who got engaged during Snooki's pregnancy, celebrated baby Lorenzo's baptism with close family and friends. Fellow MTV stars Jennie "JWoww" Farley and her fiance Roger Mathews were also in attendance.
"Lorenzo is finally baptized! He did so good," Snooki tweeted.
In another shot the first time mom, 25, was seen posing alongside Lorenzo's stroller at the baptism reception.
"Walkin my baby around his party in style," Snooki tweeted.
The reality TV star appeared to be confident as she flaunted her 42-pound weight loss on Lorenzo's big day. She previously revealed her weight loss secrets in an interview on the "Today" show.
"The first 20 [pounds] came [off] from just breastfeeding, so that was awesome! But then I had to wait until I could work out, which was six weeks, and then I just went straight to the gym, Snooki told "Today" host Matt Lauer.
"I work with a trainer, one of my good friends Anthony, so he basically just kicked my butt into shape and he gave me these express meals which [don't] have a lot of calories," she added.
The "Snooki and JWoww" star is now said to be down to 1300 calories a day, and while she was renowned for her hard partying, she claims having a baby has put her off of alcohol.
"It's hard to drink while taking care of a baby, so I don't drink at all, really and when I do drink, I get drunk off of like three sips, so it's actually good," she said.
"I knew I couldn't party anymore, because now I'm a parent; I have to take care of someone else," she revealed. "So the partying's done, basically … But it was more about getting in shape and being a fit mom."
