It's a boy for Holly Madison and her husband, Pasquale Rotella!
The 36-year-old ex-girlfriend of Hugh Hefner confirmed the news to ET, saying, "My husband and I are very excited to add a little boy to our family. Our daughter, however, is holding out for a sister."
Madison and Rotella welcomed their daughter, Rainbow, in March 2013. They announced their second pregnancy in January by posting a sonogram photo to Instagram.
"Blessed and excited to announce @hollymadison & I have a baby owl on the way! can't wait to welcome another beautiful soul into our family & watch#rainbowaurorarotella become a big sister!" Rotella captioned the photo at the time.
Madison already loves being a mom to her adorable daughter. In October, she opened up to Yahoo Parenting about handling the subject of Playboy with the little girl.
"From Day One I've tried to raise her to know she has value, her body parts have value, and she doesn't have to do something cheap or tawdry to get attention," she said. "If she wanted to do — and God forbid she did — I would tell her my whole experience with it and I'd be honest that it wasn't what I thought it would be."
