Kim Kardashian and Kanye West welcomed their fourth child into the world last Thursday. The baby was born via surrogate and joined three older siblings: five-year-old sister North West, three-year-old brother Saint West and one-year-old sister Chicago West.

Fans of the power couple wondered what kind of name they would select for their fourth child. Another direction like North? Another city like Chicago? Or another religious name like Saint? On Friday afternoon, Kim revealed the answer on social media: The baby boy's name is Psalm West! ("Should have been Wild smh," one Twitter user joked.)

"Psalm West," Kim wrote on social media, alongside an image of the sleeping infant. An attached note read: "Beautiful Mother's Day with the arrival of our fourth child. We are blessed beyond measure. We have everything we need."

The reality TV star announced she was going to have a fourth child in January. "Kim and Kanye have known for awhile and are very excited," a source explained to E! News. "They had one male embryo left and are thrilled it has worked out. Kim always wanted four kids and having two boys and two girls feels perfect. They were very happy with the entire experience the first time and are so grateful to have one more baby."

The family of four doesn't plan on any future additions, according to an interview with Elle in 2018. "I don't think I could handle more than [four children]," Kim said. "My time is spread really thin. And I think it's important that in all couples, the mom gives the husband as much attention as the kids."

Congratulations to KimYe!

Chicagoans poked so much fun at Kim and Kanye 

Others thought Chicago West sounds like a hospital (?!)

One Twitter user came up with an elaborate conspiracy theory 

another just thought it summed up 2018 

While some people just loved the name 

Are Kim Kardashian and Kanye West preparing to welcome another little one into their family?

If reports are anything to go by, we are indeed about to be blessed with another Kardashian-West baby!

US Weekly have alleged that congratulations are in order, claiming the couple are expecting their fourth baby via surrogate - a baby boy!

A 'source' reportedly told the magazine that Kimye's baby is due "in very early May," with another 'insider' stating that Kim has "always wanted four kids." According to the same report, the celebrity couple only had one more fertilised embryo left and decided to use it.

As it stands, there are no further details and neither Kim, nor her rapper husband, has confirmed the news.

The famous pair already has three children together: five-year-old North, three-year-old Saint, and baby Chicago.

Their youngest child was born on January 15, 2018, via surrogate, something that Kim choose after suffering from placenta accreta and preeclampsia during her previous two deliveries.

However, watching another woman carry her child wasn't easy for the Keeping Up With The Kardashians star.

After the birth, the 38-year-old took to her website to share what it was like to use a gestational carrier, naming it "so hard".

"Having a gestational carrier is definitely different, but anyone who says or thinks it’s the easy way out is completely wrong," she wrote. "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: "There are so many reasons why a couple might need a gestational carrier or a surrogate. 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. The feeling at the end of the whole process is so rewarding. 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. We are so excited to finally welcome home our baby girl."

In an episode of Keeping Up With the Kardashians last October, Kim was also seen talking to her friend, Larsa Pippen, about her future family plans, saying: "Kanye wants to have more. He's been harassing me. He wants like seven. He's like stuck on seven."

She confessed she was reluctant to follow through with this plan though, saying: "[Seven kids is] crazy. I could never, especially in like the world we live in. I've been kinda hesitant about having more kids because it literally keeps me up at night, thinking about how my kids will survive in a crazy world like this."

So, are congratulations in order...? Watch this space.

Kim Kardashian might well be one of the most famous people in the world, but that doesn't mean that she isn't a great parent. As anyone who follows her on social media will tell you, Kim absolutely loves being a mom, and regularly uploads snaps of herself and her kids, North, Saint and Chicago.

However, Kim has now shocked her fans by announcing some wonderful news: Kanye and Kim are expecting a fourth baby together. Not only that, but they seem to have already picked a name for the child.

In a recent appearance on Watch What Happens Live with Andy Cohen, Kim confirmed the couple were expecting a boy via a surrogate mother, adding that she'd let the cat out of the bag over the Christmas period while under the influence.

She stated: "I got drunk at our Christmas Eve party and told some people. I can't remember who I told because I never get drunk," before adding that the due date would be "sometime soon."

A source close to the couple has allegedly told E! News: "The surrogate is well into the pregnancy. She is due in May and everything looks good. Kim and Kanye have known for a while and are very excited. They had one male embryo left and are thrilled it has worked out. Kim always wanted four kids and having two boys and two girls feels perfect."

Kim gave birth to her daughter North West, on June 15, 2013, and her son Saint West, on December 5, 2015, but decided to use a surrogate for her third child, Chicago West, after both pregnancies proved to be difficult ordeals.

While pregnant with North she suffered from preeclampsia, a disease which causes high blood pressure which can lead to a low blood platelet count, impaired liver function, kidney dysfunction, swelling, and shortness of breath.

As a result of this, Kim was forced to deliver North after 34 weeks, and also suffered from placenta accreta after delivery, which caused heavy bleeding. She had to have surgery to remove the placenta and subsequent scar tissue as a result. Following this, doctors apparently advised her not to become pregnant again; the couple's third child was born via surrogate on January 15, 2018.

In the same interview, Kim also opened up about her well-publicized feuds with Taylor Swift and Drake. She revealed that she and Tay-tay have more or less buried the hatchet over the whole lyrics scandal, but also mentioned that she's still antagonistic towards Drake, especially after Kanye claimed that Drake threatened his family.

Perhaps they'll be able to kiss and make-up in the new year, but somehow I don't think so. Here's a little lesson for you Drake: don't mess with a momma bear.

A little under a year ago, Kanye West and Kim Kardashian welcomed their third child, Chicago, who was delivered by a surrogate.

"Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl," Kim wrote on January 15th, 2018. "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."

Now, Kanye has appeared to confirm rumours that he and his wife are expecting their fourth child - also via surrogate.

Whispers about baby number four were reported by Entertainment Weekly after multiple sources claimed the couple were expecting a baby in "very early May". Now, fans believe that Ye confirmed another baby was on the way after photographers wished him congratulations, and he said, "Thanks, bro."

Back in August, however, Kim K denied talk that she and Kanye were planning on having another child "as soon as possible".

"None of that was true," she said of the rumours. "I've been really open about it and talked about it on our show. We start filming season 16 next week, so if I think about it more and it's gonna happen, you'll definitely see it on the show. But as of now, no. I gotta live with three for a second. If it were up to my husband we'd have like seven. Maybe four is all I can handle. I don't know, maybe three is all I can handle."

Kim has spoken out before on her reasons for not giving birth to Chicago herself, and her decision still stands with baby number four.

During her first pregnancy with North, she suffered from preeclampsia - a condition which gives the expectant mother high blood pressure and severe headaches. She also struggled with placenta accreta - a condition in which the placenta grows too deeply into the mother’s uterus, becoming inseparable from the uterine wall. After birth, when the placenta is supposed to be expelled from the uterus, it fails to detach - something which can be hugely scary for the mother.

"Having a gestational carrier is definitely different, but anyone who says or thinks it’s the easy way out is completely wrong," Kim said in the past.

"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 also expressed her gratitude to the surrogate that carried her third child.

"Our gestational carrier gave us the greatest gift one could give. 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. We are so excited to finally welcome home our baby girl."

Kim and Kanye will not be using the same surrogate as they did with Chi, however, as she has just had a baby of her own.
