He is the middle class singer who likes to sing the blues.
So perhaps John Mayer's music may sound a little more authentic now he is being sued over allegedly receiving money from a fraudulent investment operation.
As much as $465,000 was handed over to the star's representatives by a Ponzi scheme ran by notorious criminal Frederick Darren Berg.
He was given an 18-year-sentance in February for duping investors out of more than $100m through his investment company.
According to TMZ, Mayer was drawn into the frame when the trustees charged with recovering as much of the stolen money as possible decided to sue those who had benefited.
New legal documents show he is one of the people who received dirty money after a booking agency was allegedly paid by his company.
It is claimed Grabow & Associates, and their client and Mayer by extension, are in possession of as much as $465,000.
The agency specialises in booking entertainment for corporate and private events, and set up the Your Body is Wonderland singer with a money-spinning appearance in 2008.
Mayer's lawyer said: 'John Mayer performed at a corporate event in 2008 and was paid for his services.
'The opportunity was brought to John through his talent agency, CAA.'
A ruling has yet to be delivered on the case.

Frederick Darren Berg was sentenced to 18 years in prison for defrauding hundreds of investors of more than $100 million through the Meridian Mortgage investment funds he ran for nearly a decade.
U.S. District Court Judge Richard A. Jones imposed the prison term recommended by Berg's plea agreement.
He told him: 'I'm not sure how you live with yourself, with the damage that you caused.'
Judge Jones noted that the lead defendant in a $90 million Ponzi scheme previously considered Washington state's largest fraud received a 20-year sentence.
But he said the slightly shorter term for Berg was appropriate since he'd mostly cooperated with prosecutors and bankruptcy trustees unravelling the labyrinthine workings of his firm.
