The Kardashian klan has officially expanded with Kim Kardashian West announcing that her third child with husband Kanye West has arrived via surrogate. The baby girl was born at 12:47am on January 15, weighing in at 7lbs 6oz. Kardashian West announced the news on her website.

"Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl. 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."

This is the Kim Kardashian and Kanye West's third child together, joining four year-old North West and two year-old Saint West who were both conceived naturally and carried by Kim. The news of the birth follows Khloé Kardashian's announcement in December that she is expecting her first child with boyfriend Tristan Thompson. Half-sister Kylie Jenner is also rumoured to be pregnant, however the family have remained tight-lipped on the rumours.

Now it is a waiting game for what the baby girl's name could possibly be. One thing's for sure; it's going to be a wild one.
