Kim welcomed Chicago back in January 2018, by way of a surrogate. Kim and Ye are also parents of daughter North West, 8, and sons Saint West, 6, and Psalm West, 2.

“Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl,” Kim said at the time. “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.”
