The red-headed reality star – who recently passed the five-month mark in her pregnancy – uploaded her latest ultrasound scan picture to Instagram on Monday night (19 May).
Snooki joked of her baby's pose: "My baby girl! She's healthy and look, she's already applying lipstick! #mygirl."
The 26-year-old announced her second pregnancy in April, saying that she and fiancé Jionni LaValle are thrilled to be giving son Lorenzo, one, a sibling.
Shortly afterwards, she confirmed it would be a baby girl.
It will be a busy few months for Snooki. Not only will she be welcoming her second child, but she has Lorenzo's second birthday celebrations in August to organise, she's moving into her "dream home" with Jionni and, this autumn, she's walking down the aisle.
Snooki and long-time love Jionni became engaged in 2012, and plan to marry in New Jersey later this year in a Great Gatsby-themed ceremony.
"I picked out my bridesmaid dresses last week and I cannot wait!" she told fans in March. "They are beyond gorgeous and going to look fabulous on everyone! My bridesmaids all have different body types, so I wanted to make sure the dress that I picked would look good on everyone.
"My next step is to ask my girls, and then figure out their jewellery and hair! Obviously I want them to look like my theme – Gatsby. I'm now searching some good hair styles from the 20′s, something very elegant and classy but sexy at the same time. For make up I'm thinking the girls have a natural, sexy look with a red lip."
