Chicago West made her public debut in Kylie Jenner's baby announcement video.
Kim can be seen handing newborn Chicago over to a pregnant Kylie.
“She looks completely different,” Kylie, 20, says “She’s so little.”
Kylie's BFF Jordyn Woods then asks if Kim has figured out a name.
"I think we're going to go with Chicago," Kim replies.
Kim and Kanye welcomed their third child on January 15, just weeks before Kylie welcomed her daughter.
