Kim Kardashian West shared the name of her and Kanye West‘s newborn daughter via her app and website on Friday. While she didn’t explain the reasoning behind the name choice, West, notably, was raised in Chicago. The name news comes four days after the baby girl’s birth via surrogate. Kardashian West shared via her website Tuesday that the spouses’ daughter was born Monday at 12:47 a.m., weighing 7 lbs., 6 oz. “Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl,” the new mom of three — who also shares son Saint, 2, and daughter North, 4½, with West — wrote in a post titled “She’s Here!” “We are incredibly grateful to our surrogate who made our dreams come true with the greatest gift one could give and to our wonderful doctors and nurses for their special care,” she added. “North and Saint are especially thrilled to welcome their baby sister.” Want all the latest pregnancy and birth announcements, plus celebrity mom blogs?
