Jenni "JWoww" Farley is expecting a little guidette! The former "Jersey Shore" star told US Weekly that she and her fiancé Roger Mathews are having a baby girl due in July.

The 27-year-old reality star told US that she was "super excited and super emotional"  - also a little shocked  - when she found out she was pregnant with a girl.  

"I pictured a boy this whole time, so when I saw 'girl' on the paperwork, I was like, 'No way!' But deep down I think I knew," she said. "[Snooki's son] Lorenzo is gonna have a BFF, and I couldn't be happier!"

Snooki is also excited about the news tweeting to her best friend that finally they go shopping for baby clothes.

"YAY finally I can go shopping with @JENNIWOWW for BABY GIRL THINGS! Lorenzo's so excited!"

Farley announced on Christmas Day (Dec. 25) that she and Matthews were expecting their first child together. In a post on her blog she thanked fans for the support telling everyone that it was the definitely the best Christmas present she received.

"She will be my best friend and daddy's little girl," Farley told US. "I can't wait for everything from her first steps to her first dance class."

One thing the MTV star isn't too excited about is those pesky teenage years telling the magazine that she knows she's going to have her work cut out for her.

"I was a teenage girl once, and, boy, do I know how sneaky we can be!" she said. "Karma is gonna kick me in the butt with her!"

Matthews, 37, hasn't stopped talking about the pregnancy, Farley revealed. He's so excited that he is already thinking about what kind of gift the daughter-to-be would get for a sweet 16.

"I'm like, 'Pump the brakes! Let's get through the first 16 months!'" Farley said. "He was just saying today what kind of car she'll get for her sweet 16 if she gets good grades."

The reality star has not revealed if they have picked out a name for the baby girl.
