Baby on board! Holly Madison and her husband, Pasquale Rotella, are expecting their second child together, a rep for the former Girls Next Door star confirmed to Us Weekly on Friday, January 22.

Married since September 2013, Madison and entrepreneur Rotella are already parents to 2-year-old daughter Rainbow Aurora Rotella, who was born in March 2013.

For Rainbow’s second birthday last March, the Down the Rabbit Hole author shared several Instagram shots revisiting her daughter’s birth, including a screen grab from her 2013 E! TV special, Holly Has a Baby.

“Two years ago!!!!” she captioned the sweet shot of herself and Rotella fawning over baby Rainbow moments after her birth.

The blue-eyed toddler even received a special cake in the shape of the famous meme PizzaCat.

“Can’t wait til Rainbow sees her cake. #PizzaCat #FavoriteCharacter,” Madison captioned the photo.

The pregnant reality star will be busy these next few months. According to a source, a TV show based on Down the Rabbit Hole is currently in development, and the former reality star will release a second book, Vegas Diaries, this spring.
