Flo Rida Vs Ex-Assistant

A woman named Mahogany Miller just sued the rapper -- claiming she busted her ass as his administrative assistant ... and in exchange he paid her less than a high school babysitter.

In her suit, Miller -- who claims she started the gig back in August -- alleges she eventually confronted her boss over the long hours and low wages ... and she was FIRED less than 24 hours after raising the issue.
