The reality favourite and fiancé Jionni LaValle announced the sex of their second child on Thursday (8 May). They are already parents to a son, Lorenzo, who is one.
A thrilled Snooki announced the sex via her official website, sharing the moment she discovered the gender via a video showing how Jionni broke the news to her.
He filled a bucket with balloons which Snooki opened to reveal their colour was pink. She joked: "Oh God, kill me! I don't know how I feel about it. I'm terrified! But really excited."

Snooki later told ABC News she is "excited" about having another girl in the family.
"I'm excited about having a little best friend to shop with and just do girlie things with!" she said.
Snooki also joked that Jionni is "nervous" about dealing with a girl, saying: "Like every father having a daughter is! They are more complicated!"
The red-haired star, 26, has just passed the five-month mark in her pregnancy and says it's been going smoothly so far and remaining active.
"This is so weird but I've been in such good moods lately! Mostly in part because I'm working out and my endorphins are awesome, but this pregnancy is so much easier than my first!"
Snooki's best friend and Jersey Shore co-star Jenni 'Jwoww' Farley is also expecting a baby girl so we imagine they'll have plenty to talk about! And just maybe we'll see the adventures of Snooki Jr and Jwoww Jr on our screens in the future!
Snooki gave birth to first son Lorenzo in August 2012 and used her experiences as the basis for new book Baby Bumps: From Party Girl to Proud Mama, and all the Messy Milestones Along the Way, which aims to give expectant mums an honest look at pregnancy.
No doubt she'll add a new chapter when baby number two arrives!
