Amber Rose can drown out all the critics of her new emoji app by stuffing $100 bills in her ears … ’cause she just made $4 MILLION off the damn thing.

Sources close to Amber say she got a fat check just for signing on with the company that developed the app. That’s not all … we’re told the MuvaMoji raked in over $2 million on its opening day, and she’s getting a cut of that too.

As for haters accusing her of ripping off emojis from Kim Kardashian‘s app … Amber’s adamant there was no attempt to imitate or copy.

We’re told she’s confident the app perfectly reps her personality — from the big booties to the stripper pole.
