"My baby's gonna be naturally tan," the 24-year-old reality star told Us Weekly at the MTV Upfronts in NYC Thursday. "If you look at me and Jionni (LaValle), we're very dark, so luckily the baby will be very dark."
Polizzi's Jersey Shore costar Paul "DJ Pauly D" DelVecchio joked that "she'll have to wait until her baby is 2 or 3" before she introduces her child to the second phase of GTL.
"Just like Toddlers & Tiaras! They spray tan those babies," Jenni "JWoww" Farley, 25, added. "I saw them do that!"
Polizzi then assured Us, "I won't be spray tanning my baby."
She will, however, be dressing her baby in typical Jersey fashions. "If it's a girl, animal print everywhere and blinged out everything," Polizzi said. "If it's a boy, I would dress him like Pauly."
Polizzi added that she hasn't been wearing maternity clothes yet. "I'm so skinny that I can wear larges or extra larges. I only just bumped up to a medium," she revealed. "I'm five months and you can't really see anything. It's gonna pop up in like a week."
The pregnant star told Us that she's afraid her baby bump will become as large as Jessica Simpson, who is due any day. "I would die if I were her size," Polizzi laughed.
Joked DelVecchio, 31: "She's like 45 months pregnant right now!"
Unlike Simpson, 31, Polizzi won't be pigging out on buttered Pop Tarts. "She said she indulged in everything that she wanted," the MTV star said. "I'm trying to each healthy -- fruits, lots of jelly and Italian ices. Nothing fattening at all."
