JWoww and Snooki are "petrified" of having baby girls.
The former 'Jersey Shore' co-stars, who are both pregnant, are afraid of having daughters because they are worried they will inherit their wild personalities.
JWoww - real name Jenny Farley - is set to give birth to her first child, a baby girl, in July with her fiancé Roger Mathews, and admitted: "I'm petrified!"
She added: "Its funny because Roger will lay his head on my stomach and she will just drop kick him right in the ear. It's cute. He gets to feel it. Once we found out we were having a girl, he lost half his hair and he aged 20 years."
Meanwhile, Snooki, who already has a 20-month-old son Lorenzo with her fiancé Jionni LaValle, hasn't found out the sex of her second child, due in September, but "isn't ready" to have a daughter.
She told UsMagazine.com: "They are going to be raging crazy women! They are going to be just like us. That's why I'm scared to have a girl."
The 26-year-old star - real name Nicole Polizzi - thinks her best pal is going to be a great mother.
She said: "I know she is going to be a great mom. She took care of me for four years on 'Jersey Shore.' The whole labour thing she is really nervous about but anybody is nervous about that."
But JWoww hates being pregnant.
She said: "(Snooki) loves being pregnant right now and I f**king hate it. I'm not a fan of pregnancy right now with my thighs touching and my boobs changing but I know it will be worth it and hopefully I get back to that really quickly."
