The 34-year-old tweeted on Tuesday: "Thank you so much and my apologies on the spelling error, this expecting Mommy is a tad sleep deprived. ;-)"
Kim made the mistake on Saturday, when she begged the fashion brand not to discontinue her favourite foundation.

Kim Kardashian blamed sleep deprivation for her spelling mistake
"Why did Georgio Armani discontinue my favorite foundation??? I'm on my last bottle & everyone I know uses this!!! Please make it again!" she tweeted.
While Kim was corrected on her spelling by the official Armani Twitter account, they did promise to send her the foundation she wanted.
"@KimKardashian Dear Kim – let us know which one you need and we'll send it to you. And Mr. Armani's first name is Giorgio," they wrote.
The Keeping up With the Kardashians star is famed for her flawless make-up and told Into the Gloss earlier this year that she loves using Armani's Luminous Silk foundation.
Kim is set to offer fans the opportunity to recreate her beauty look by hosting a make-up masterclass with her longtime make-up artist Mario Dedivanovic in July. Announcing the news that she will be the star of the class, Kim posted a picture of the invite to Twitter on Thursday.
"Make Up Class Alert Mario & I will be in LA July 25th to share all of our make up tricks & beauty routine!" she captioned the shot.

However there is one catch – a ticket for the class costs $800. Fans unable to attend the special masterclass will still be able to access Kim's beauty tips with the tutorials she is planning to share on her new website over the summer.
Kim recently revealed: "I'm shooting a make up tutorial today that will post on my new website when it launches this summer! Going to have tons of tutorials!"
