The former Playboy model
and her husband, Pasquale Rotella, welcomed their second child, a son, on Sunday!
The couple announced the news Monday night, each sharing a heartwarming photo of their newborn's tiny hand.
Madison posted an adorable pic of her son's fingers wrapped tightly around her own, which she captioned simply with a trio of heart emjois.
Rotella was more verbose in the caption of his sweet snapshot, which showed his son's hand resting on his own.
"What an incredible week," he shared. "Yesterday Holly, Rainbow & I welcomed a healthy 8-pound, 14-ounce baby boy to the family. Now I'm holding my beautiful son at the hospital reading amazing birthday wishes from all of you. Definitely one of the most memorable weeks of my life!"
Rotella promised that the family will be sharing a ton of photos of their brand new bundle of joy once they take him home.
Congrats to the happy couple!
