Kim Kardashian West stands, arms folded and lips pursed, on the latest cover of Forbes magazine, chosen for a reason you wouldn't normally associate with the reality television star - her business savvy.The magazine is profiling ''The New Mobile Moguls" and Kardashian has made $45-million (R640-million) from just one game, a game that rakes in more than $300-million a year.And that's before you add Kimoji, her Kim Kardashian Emoji app, into the calculations.
