The secret is out – Holly Madison is expecting a girl!

Her boyfriend, Pasquale Rotella spilled the beans on Tuesday, tweeting a sonogram of the baby and writing “Off to Amsterdam and I already miss my girls.”

Looks like he missed the memo that Madison didn’t want to share the sex of the baby…

“We’re not telling anybody yet, but we found out and I’m really excited!” the Peepshow dancer told reporters earlier this month.

Following Rotella’s tweet, the 32-year-old mom-to-be did confirm the news to People but she still has one secret that she’s managed to keep under wraps – the baby’s name.

“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,” she said (referring to Gwyneth Paltrow’s daughter). “I don’t like common names at all. If I’ve heard it before on somebody more than one time, it’s out!”

Madison, who is a former Playboy Playmate and starred in the reality show “Girls Next Door,” is thrilled about her pregnancy. In past interviews, she gushed about how she “always wanted to be a mom.”

Can’t wait to find out what she names her little girl!
