The pregnant Jersey Shore alum, 27, was "super excited and super emotional" to find out the gender, she tells Us. "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 says. "[Snooki's son] Lorenzo is gonna have a BFF, and I couldn't be happier!" See throwback pics of JWoww here.
"She will be my best friend and daddy's little girl," the first-time mom-to-be adds. "I can't wait for everything from her first steps to her first dance class."
One thing she's less excited for? Those dreaded teenage years. "I was a teenage girl once, and, boy, do I know how sneaky we can be!" Farley quips. "Karma is gonna kick me in the butt with her!"
Mathews, 37, is already thinking of ways to keep their daughter-to-be on the straight and narrow, she jokes. "He was just saying today what kind of car she'll get for her sweet 16 if she gets good grades," the MTV star tells Us, noting that he "hasn't stopped talking" about the news. "I'm like, 'Pump the brakes! Let's get through the first 16 months!'"
