On Wednesday, Amber Rose released her app MuvaMoji, which is a lot like Kim Kardashian's Kimoji, except, you know, with Amber instead of Kim.

Kim Kardashian released a similar app in December 2015, and Kardashian fans are angry because they think Amber copied Kim's idea. Rose, who dated Kim's husband Kanye West from 2008 to 2010, probably couldn't care less what Kardashian fans think because, according to TMZ, she's already made $4 million off the app in the two days since it's been released.
