Flo Rida has been sued by bosses of a security company who claim the rapper failed to settle a bill for an alarm system at his Florida home.

Executives at ADT allege their operatives installed a state-of-the-art security system at the star's Miami mansion in 2009 and received the full deposit of $19,366 but Flo Rida failed to hand over the remaining balance of $38,733.

They have filed a lawsuit demanding payment plus interest amounting to $47,134.

However, the rapper claims he never authorised the deal and the contract was signed by a man called Lee Prince, who reportedly worked as the star's manager, according to TMZ.

A judge has yet to rule on the case.
