Kim Kardashian West has revealed the name of her third child with husband Kanye West; Chicago.

Kardashian West took to Twitter to reveal the name of their daughter, whose birth was announced on Monday.

"Chicago West," the tweet read.

It is thought that they chose to name their daughter after the city as this is where Kanye West was raised, having been born in Atlanta.

On Monday, Kardashian West shared the couple's baby joy on her official website, posting, "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."

The couple is already parents to four-year-old North and two-year-old Saint, who are said to be "especially thrilled to welcome their baby sister."

They chose to use a surrogate to carry Chicago as Kardashian West suffered from the high risk pregnancy conditions pre-eclampsia and placenta accreta during her previous pregnancies.

She said in a post on her app that "doctors said that it wasn't safe for my, or the baby's, health to carry my own".

The 37-year-old reality TV star said that she and her husband decided to use a gestational carrier meaning the baby is "biologically mine and Kanye's".

She wrote: "Having a gestational carrier is definitely different, but anyone who says or thinks it's the easy way out is completely wrong.

"People assume it's better because you don't have to deal with the physical changes, pain or complications with delivery, but for me it was so hard to not carry my own child, especially after I carried North and Saint."

She continued of their surrogate, whose identity has not been revealed: "We have a great relationship with her and trusted her completely throughout the entire process.

"I'm so grateful for modern technology and that this is even possible. It's not for everyone, but I absolutely love my gestational carrier and this was the best experience I've ever had.

"Our gestational carrier gave us the greatest gift one could give."

She added: "The connection with our baby came instantly and it's as if she was with us the whole time.

"Having a gestational carrier was so special for us and she made our dreams of expanding our family come true."
