Calloway has two daughters, and by the looks of the pictures, the family could not be happier to welcome their new member.
Calloway posted a picture from the Los Angeles hospital, captioning the photo, "In the place to be a week and change early! Welcome to the world A.L.C III."
He also shared a picture of the little one with his two older sisters, Amy Belle and Ava Claire.
Congratulations to the whole family!
Look back at Calloway on 106 & Park on #WaybackWednesday above.
