And baby makes five.
On what will be a year full of stork arrivals for the Kardashian clan, Kim Kardashian West and her husband, Kanye West, announced the birth of their daughter via surrogate on social media Tuesday.
"Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl," Kardashian wrote on Twitter. "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."
Kardashian West did not reveal the new arrival's name, who weighed in at 7 pounds, 6 ounces. It was unclear where the baby was born.

The reality star and makeup mogul suffered from placenta accreta, a potentially life-threatening complication, during her two pregnancies.
The newest member of the family will have plenty of company. Kardashian's sister Khloe is expecting later this year and her younger sister Kylie is rumored to be pregnant, although she hasn't yet confirmed the news.
Khloe Kardashian was one of the first to respond on social media.
