Kim Kardashian West [VIDEO]shared the name of her and Kanye West's newborn daughter via her app and website on Friday but she didn’t explain the reason why she chose the name. The reality star shared the news four days after the birth of Chicago via a gestational surrogate. The little angel was born at a Cedars-Sinai Medical Center in Los Angeles on Monday, January 15. She was delivered by the family most trusted doctor, Paul Crane, without any complications, according to CNN. The mother-of-three was the first to hold the newborn, followed by her husband.

The secret behind the name Chicago West

After his parents divorced when he was three-years-old, Kanye and his mother, moved to Chicago.

He spent the early moments of his life in Oak Lawn and references the city in his songs most often, and especially in the “Homecoming” song in 2007 in which he featured Chris Martin. While Chris Martin sang about sparks and fireworks, Kanye rapped about meeting a girl named Windy which is a metaphoric reference to the city of Chicago. He made this clear when he said, “In case you didn’t understand; I was talking about Chi-City.”

After Kanye and his mother moved to Los Angeles, she underwent cosmetic surgery. This resulted in complications that led to her sudden passing. In an interview in 2015, the pop star revealed that “If I had never moved to Los Angeles. She’d still be alive.” Since then, the father-of-three still blames himself for the demise of his mother. He went further to start a Charity in her honor, to which he donates handsomely from time to time.

The reason behind naming their other kids

We knew that Kim and Kanye weren’t exactly going to stay traditional with their choice, considering they named their 4-year-old daughter North West and their two-year-old son Saint – but Chicago has really thrown us all for a loop. However, it seems the Kardashians are way more on board with the unusual moniker.

According to TMZ, Kanye West's decision to name their four-year-old daughter North West was because of her entrance into this world came alongside a high point in their lives. Kim Kardashian's complicated pregnancy resulted in the naming of her second child Saint West, while Chicago West seems to be a more special gift to the couple - as photos of the pop star and father-of-three at his office on Wednesday circulated the internet and he was seen smiling from ear to ear.
