The 32-year-old star debuted her MuvaMojis, a set of 900 symbols available from Apple and Android app stores on March 31 and the model is said to be set to receive a cut of the profits after the successful start.
Rose has already made USD 4 million out of the app after signing a deal with developer Appmoji.
Her app features many designs, including one glittery emoji stating 'Free Kesha', in support of the "Tik Tok" hitmaker who is currently involved in a very public legal battle with her record label to be released from her contract over allegations of sexual abuse she has made against producer Dr Luke.
