Rap sensation Flo Rida has been ordered to pay $400,000 after cancelling a performance at an Australian music festival at the last minute.

Back in May, the 'Wild Ones' hitmaker was slapped with a lawsuit for failing to attend the Fat As Butter event in Newcastle, New South Wales and at a hearing last week it was decided that he should pay compensation for his actions.

Judge Judith Gibson said: "All of these angry patrons demanded a refund, sometimes in confronting language, such as: 'You guys didn't deliver what you advertised and I paid for.'"

"Sponsors were lost as news of the no-show spread far and wide through the use of social media such as Facebook, Twitter and YouTube. The no-show by Flo Rida damaged the trading reputation of the plaintiff, impacting its ability to stage future events, attract patrons and compete with rivals in the music event industry."

Flo Rida and VIP Entertainment and Concepts now have to pay $380,400 in damages and $37,745 in legal fees.
