It's about time!

On Nov. 2, first-time mother-to-be Holly Madison shared a picture of her growing baby bump on her Celebuzz website. "Damn! My belly popped out of nowhere!" the Playboy model wrote. "I just hit the 6 month mark and it's like my belly got big overnight!"

Madison, 32, and her boyfriend, Electric Daisy Carnival founder Pasquale Rotella, 38, are expecting a baby girl. The Peepshow dancer broke the news of her pregnancy exclusively to Us Weekly in August, saying she had "always wanted to be a mom" and hopes to have "six kids" with her beau of less than a year.

The Alaskannative -- who split with Hugh Hefner, 86, in 2008 because he could not have kids -- isn't pigging out while pregnant. "I try to eat healthy for the baby -- I love vegetable and fruit smoothies," Madison told Us. "But my downfall is french fries. My excuse is they settle my stomach!"

For now, Madison is focused on prepping her little girl's room. "I'm really excited about decorating the nursery," she said. "We've already started buying some things."
