It’ll be a girl for Jenni "JWoww" Farley.

The pregnant "Jersey Shore" alumna and "Snooki & JWoww" star reveals she and fiance Roger Mathews are expecting a daughter in July.

Farley, 27, told Us Weekly, "She will be my best friend and daddy's little girl. I can't wait for everything from her first steps to her first dance class."

The reality TV star broke the news that she was expecting on Christmas Day. She'll be the third "Jersey Shore" cast member to become a parent -- Nicole "Snooki" Polizzi has a son and Paul "Pauly D" DelVecchio has a daughter.

"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," Farley said of finding out her baby’s gender. "[Snooki's son] Lorenzo is gonna have a BFF, and I couldn't be happier!"
