Show Caption Hide Caption Kanye and Kim name their third child Kanye and Kim Kardashian West reveal daughter's name is Chicago. The couple welcomed the baby girl into the world via surrogate.

It's official: The newest member of the Kardashian clan, the baby girl born to Kim Kardashian and husband Kanye West, will be named Chicago West.

Kim posted the news on her social media accounts Friday.

How come? Kim didn't say, but Chicago, America's second-largest city, is Kanye's hometown. It's also where he first established his charitable foundation, now called Donda's House (for his late mom).

Kim tweeted the baby's likely nickname — Chi — adding it to her two other kids' names, North, 4, and Saint, 2.

Chicago (the baby) was born Monday via a surrogate at 12:47 a.m. and weighed 7 pounds, 6 ounces, according to a statement Kim posted. She did not say where the baby was born.

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

Kardashian and West hired a gestational surrogate because Kardashian's doctors strongly advised her not to go through a third pregnancy, as she discussed on her show, Keeping Up with the Kardashians.

She suffered from placenta accreta, a painful and potentially life-threatening condition that makes childbirth difficult because the placenta is attached too deeply to the uterine wall.

Place names for celebrities' babies are not unusual: Boston and Brooklyn, India and Moroccan, Dallas and London, Ireland and Scotland, Indiana and Tennessee.

But Chicago for a celebrity baby girl appears to be a first.
