Kim Kardashian and Kanye West always seem to chose some unique names for their children. First North, then Saint and for baby #3, Chicago which is also Kanye’s hometown … but it’s a good bet she’ll be known by a certain nickname.

Kim announced the name on her app by simply posting “Chicago West.”

Kim and Kanye had their third child via surrogate, who gave birth Monday to a healthy girl weighing 7 lbs. 6 oz. Kim was in the delivery room during the birth, and sources are told she was the first person to have skin-to-skin contact with the baby.
