Remember when Kim Kardashian launched her own mobile game app? It made Kim/her momager a BUCKETLOAD of cash - $43.3 million last year, to be precise.
So unsurprisingly, Kim's little half-sisters are getting in on the lucrative iPhone app market: Kendall and Kylie are tapping in to the legions of fans who want to pretend to be the famous family ALL DAMN DAY.
They tweeted and Instagrammed joint announcements about a new mobile app, with Kendall saying "We couldn't wait to tell you any longer! Excited to announce that we are working on our own mobile game! #KendallKylieGame #staytuned"
Both Kendall and Kylie have already starred in Kim's Hollywood app - but now it sounds like the sisters are branching out on their own.
Not much more info has been published at the moment - so we have no idea what the app will entail. Will fans be able to try their hand at Kylie's badass lip-lining skills? Or walk the runway and hang out with Cara D like Kendall? We don't know - but we're sure the app will be just as successful as Kim Kardashian: Hollywood.
