Kim Kardashian has launched yet another successful business venture and, as always, husband Kanye West is in her corner. The "All Day" rapper took to Twitter Tuesday to celebrate the launch of his reality star wife's latest app, Kimoji.

Kanye, 38, praised Kim, 35, for her innovation in a rare tweet from his personal account. The rapper called the Kimoji app a "dope" idea, adding that he was proud of her. Accompanying his sweet message was a screen grab, showing one of the many Kim-themed emojis available in the app. The photo is, of course, modeled after one of her famous selfies.

Kimoji was launched Monday after very little promotion from the star of E!'s "Keeping Up With the Kardashians." One day prior to the apps' release, Kim shared a photo on Instagram in which she announced the top secret project. Even without the constant push on social media the app managed to completely crash Apple's app store shortly after launching. Kim tweeted her excitement, thanking her fans for their dedication. She later announced that Apple was working hard to get the store back up and running and that her team was making some major tweaks to the app, fixing search features and more.

This is the second time Kim has dabbled in technology. The "KUWTK" star released her first app, a game called "Kim Kardashian Hollywood," in 2014. The animated role-playing game allowed users to go on missions as her, interacting with her famous friends, attending star-studded events, and reliving major milestones in her life. As "Kim Kardashian Hollywood" grew in popularity Kim expanded the character base by adding Kanye, her mother, Kris Jenner, and sisters Kourtney Kardashian, Khloé Kardashian, Kendall Jenner and Kylie Jenner.
