Mason was born in Los Angeles in 2009 - andcameras were in the delivery room(thanks to dadScott Disick) as MomKourtney Kardashianliterally pulled him out at the end of her delivery. Sisters Khloé andKim Kardashianand momKris Jennerwere in the room, too, tearing up at the arrival of the first member of the family’s next generation.
“Scott was filming it for our own purposes, like for a home movie,” Mom shared years later. “The birth of my son was such a beautiful experience that I really wanted to share it with people because it was my child. I remember being so terrified to give birth because you see in movies everyone is screaming and it was so crazy and my experience was amazing. I just felt something in me wanted to share that with people.”
