Kanye West is one proud hubby!
The Kimoji app quickly went straight to the top of the Apple Store chart.
"I'm so proud of my wife! This KIMOJI idea is so dope..." he captioned this tweet, adding a racy emoji of Kim taking a selfie in a revealing white one-piece bathing suit.
The icon resembles an original image posted by Kim in October 2013 where she showed off a 25-pound weight loss following the birth of her first child, North.
After Monday's launch of Kim's app, which includes the racy icon, millions of followers flocked to install it, causing it to temporarily break down.
"We worked so hard on this app & we know there are some issues due to the massive downloads that the whole tech team is so working on!" she said on Twitter.
"My Kimoji app will be up and running again soon! They are also working on fixing the search so you can easily find it!"
Seven hours later, the app was fixed.
