U.S. hitmaker Flo Rida has been slapped with a lawsuit via popular social networking site Facebook.

The 'Wild Ones' rapper, whose real name is Tramar Dillard, was due to perform at Australia's Fat as Butter music festival last October, but failed to show up and because he was given a rather hefty advance of $55,000 (£34,375) he now owes the event's promoter money.

Speaking to Australia's Daily Telegraph, lawyer Matthew Hourn explained that after trying to contact the star directly it was found to be easier to message him through the social networking site as he often updates it:

"Our process server tried arranging meetings with his agents and attended appearances in Melbourne - but due to his large entourage and security, we were unable to serve him personally."

Check out the official audio for Flo Rida's track 'Whistle', which will be on his new album, below:
