The reality star gave birth to their child, the couple's second, on Saturday morning.
"KANYE AND I WELCOME OUR BABY BOY!" Kim wrote on her website and app.
"Mother and son are doing well," the message stated.His name was not revealed.
In her post, Kim also shared a sweet photo. Kim had one day earlier posted on social media a selfie showing her nine-month-old baby bump, saying, "Ready whenever you are lol."
The star, who was also rumored to be planning to get induced early, revealed before Thanksgiving that there was a chance she'd have to get a C-section this time around because her baby was breech, meaning his body was turned in the womb.
Fortunately, Kim was able to undergo a procedure over the Thanksgiving-holiday weekend to have the baby turned in the correct direction, head pointing down. "This weekend I checked into the hospital and underwent a procedure called an ECV (External Cephalic Version, or a Version), which is done to manually turn the baby from a breech position to a head-down position," she revealed in a Dec. blog post.
