The Keeping Up With the Kardashians star delivered the couple's baby girl on Saturday, June 15, 2013, in Los Angeles.
Check out all the details surrounding her birth!
Kim gave birth at Cedars Sinai Hospital, the same place where her sis Kourtney Kardashian delivered her little ones, Penelope and Mason.
And while it wasn't clear if Kanye was in Los Angeles prior to the birth, given that he didn't attend his Yeezus listening party last night, a source told E! News her rapper beau was right by Kim's side during the delivery.
Kim was due to deliver the baby in July, but gave birth five weeks early. However, Kim delievered the baby girl naturally and both mother and baby are happy and healthy, E! News confirms.
A source tells E! News exclusively that the baby girl weighed in at "under five pounds" and is definitely a Kardashian Mini Me: "She has dark hair. She looks just like Kim."
The proud parents haven't revealed the baby's name just yet, but a source tells E! News that Kim told friends and family in the weeks leading up to the birth that the name "will start with a K."
The E! star has also told friends she and Kanye talked about using his late mom's name, Donda, as the baby's middle name.
When the new mom found out their baby's gender, she said on the season premiere of Keeping Up With the Kardashians, "Who doesn't want a girl? They're the best. And I know that's what Kanye has always wanted, he wanted a little girl."
