The name announcement followed Kylie addressing her pregnancy for the first time in a post and video Sunday.
Someone had a question.
People also began to tell stories using names from the Kardashian/Jenner family.
For those who need a quick primer on where we're at so far on the name front:
Chicago, North, and Saint are the children of Kim Kardashian and Kanye West.
Dream is the daughter born to Rob Kardashian and Blac Chyna.
Reign, Penelope, and Mason are the children of Kourtney Kardashian and Scott Disick.
OK, here we go.
