Platinum rapper Flo Rida is being sued by ADT. The security company says that they installed a high tech security system in the rap star’s Miami mansion back in 2009. The system cost $58,000 but according to the lawsuit Flo Rida only paid $19,366.66 for the deposit and never paid the remaining balance of $38,733. ADT says that they want the balance owed plus interest totaling $47,000. ADT provided a copy of the contract to the court, which was signed by Flo Rida’s manager Lee Prince. Flo Rida refuses to pay because he says he never authorized the work despite his manager’s signature.
