Flo Rida*Flo Rida is being sued by ADT which claims that it wired the rapper’s Miami mansion with a system that included dozens of sensors, smoke detectors and at least 27 security cameras, reports TMZ.

In the lawsuit, ADT provided a copy of the contract … which was signed by a man named Lee Prince — who is reportedly Flo’s manager.

According to the lawsuit, Flo paid the initial deposit — $19,366.66 — but after the work was completed, he never forked over the remaining $38,733.

Now, ADT wants the money PLUS interest, totaling $47,134.40.

Here’s where it gets crazy — Flo Rida has fired back at the suit … saying he NEVER authorized the work despite Prince’s signature … and claims he doesn’t owe ADT a dime.

A judge has yet to rule.
