The mother-of-three revealed in a second tweet that the baby would be known as “Chi” (pronounced “Shy”).
The cameras did not show La’Reina’s face in full, but did show the surrogate interacting with Kris Jenner and pregnant sisters Khloe Kardashian and Kylie Jenner.
Kylie Jenner, who was still pregnant at the time can be heard saying: “This is so beautiful, this is so amazing,” while Kris Jenner told the surrogate: “Without you, this wouldn’t have been possible, so we can’t say thank you enough.”
Kimye are already parents to 4-year-old daughter North (known as “Nori”) and 2-year-old son Saint.
“Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl,” Kim said in a statement on her app at the time.
“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.”
Earlier this week, Beyonce appeared to take a dig at Kim Kardashian in a new rap track with husband Jay-Z and DJ Khalid.
The dig appears a reference to Kim Kardashian’s 2014 Paper magazine cover where she appeared naked and covered in oil with the tagline Break the Internet.
Beyonce made a none-so-subtle reference to the episode in her new track Top Off alongside husband Jay-Z and DJ Khalid.
“I’m the only lady here, still the realest n***a in the room. I break the internet, top two and I ain’t number two,” she sings.
Then, just in case anyone was unsure who she was singing about, Beyonce sings about the fact she hasn’t had plastic surgery, unlike the rumours around Kardashian.
“My body, my ice, my cash, all real, I’m a triple threat,” she sings.
The stars’ husbands Jay-Z and Kanye West used to be best friends but have fallen out in recent years.
West used a number of concert appearances to diss Jay-Z and Beyonce after the failed to check up on him and Kardashian after she was robbed at gunpoint in Paris.
“Don’t call me, after the robbery, and say ‘how you feelin?’ You wanna know how I’m feelin? Come by the house. Bring the kids by the house. Like we’re brothers. Let’s sit down,” West said.
