Flo Rida reportedly owes the IRS around $1m after failing to pay any taxes in the past three years.
The rapper, who has enjoyed huge chart success in recent years with his singles 'Whistle', 'Wild Ones' and 'Good Feeling', has had to put his Miami mansion on sale in a bid to clear his debts.
It is believed that Flo Rida, real name Tramar Dillard, has earned around $14million in his career.
His lawyer, Reginald Mathis, said that accountants were looking into the tax claims and that "Whatever Flo owes, he’ll pay".
