Kim Kardashian and Kanye West's family has grown.

Kim Kardashian-West opens up about her surrogate & baby number three

The couple have welcomed their third child via surrogate and the family are stoked. 

"Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl," Kim announced on her app. "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." Their daughter was born Jan. 15 at 12:47 a.m. PT and weighed 7 lbs., 6 oz., Kim added.

In late September, the reality star confirmed the exciting news that she and her husband were expecting their third child during a phone call with Khloe Kardashian.

In 2015, Kim opened up to E! News about trying to conceive after giving birth to Saint West.

"Every medical issue that you could probably have, I feel like I get, and I worry so much about it."

And during the most recent season of KUWTK, Kim confessed that she and her husband had been eager to grow their family of four.

"Kanye and I have always talked about having more kids, but after what I went through in Paris, the urgency is even greater. I'd just love nothing more than to expand my family and just know that I have this world at home that is safe. And if for some reason I left this earth sooner than I really wanted to, then my kids would have a support system at home so that I know that they would be OK if I wasn't there," she explained.

Congrats to the pair on their bundle of joy!
