Rapper Flo Rida has been ordered to pay up in a legal battle over the costs of his home alarm system. The Right Round hitmaker was sued by bosses at ADT in 2012 after allegedly reneging on a deal to have a state-of-the-art security system installed in his Miami, Florida mansion in 2009. In legal papers, lawyers for ADT claim he handed over a deposit of just over $19,000 (£11,875), but failed to settle the remainder of the $58,000 (£36,250) bill. Flo Rida insisted he never authorised the installation and blamed a former manager for signing the contract, but a judge has rejected his argument and has ruled in the plaintiff's favour. The hip-hop star must now pay ADT the amount of $31,258 (£19,536), according to TMZ.com. It's the latest legal woe for the rapper - he is also currently embroiled in a lawsuit filed against a Florida couple over accusations of a failed real estate deal.
