Holly Madison - the former girlfriend of Hugh Hefner, now expecting a baby with Pasquale Rotella - is having a little girl. Pasquale let the news slip on Twitter this Tuesday (October 16), tweeting, "Off to Amsterdam and I already miss my girls," attaching a photo of a sonogram of her baby.

Responding to a flurry of congratulations, he added "We are very excited!" commenting a couple more times on his "little fairy tale princess." We guess Rotella might find himself in hot water with the Peepshow dancer, who told US Weekly earlier this month, "We're not telling anybody yet, but we found out and I'm really excited! I'm really excited about decorating the nursery, so we've already started buying some things there." The former Playboy bunny first broke news of the pregnancy in August, saying she had always wanted to be a mom. Though Pasquale has gone and ruined the surprise, Madison still has any potential names firmly locked away. She has said, "I don't want to say what the names are, but I will say that they're very unusual. Kind of Apple-ish, along those lines." Orange? Banana? Pomegranate?

The couple will welcome their first child together in March, 2012.
