Kim Kardashian and Kanye West welcomed their third child into the world Monday. The Kardashian-Wests' surrogate gave birth to a "healthy girl weighing 7lbs 6oz," TMZ reported.

The surrogate is reportedly based in San Diego, though it's presently not known if she gave birth there or at Cedars-Sinai Medical Center in Los Angeles. Both of the Kardashian-Wests' other children, North and Saint, were born in L.A.

Shortly after TMZ's story dropped, Kardashian hit up Twitter to confirm.

"Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl," Kardashian said in a post on her website Tuesday. "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. North and Saint are especially thrilled to welcome their baby sister."

Speaking with Entertainment Tonight back in November, Kardashian detailed how the surrogate experience is not "the easy way out," as presumed idiots often argue. "I think it is so much harder to go through it this way, because you are not really in control," she explained. "And, you know, obviously you pick someone that you completely trust and that you have a good bond and relationship with, but it is still ... knowing that I was able to carry my first two babies and not, you know, my baby now, it's hard for me."

Kardashian, whose new ScreenShop app launched last year, is currently in the middle of another season of Keeping Up With the Kardashians on the E! network. In the most recent episode, another member of the Kardashian crew—Khloé—chronicled the moment she found out she too was expecting a child.

Congrats to the family.
