Music producer Swizz Beatz has fallen foul of U.S. tax authorities after allegedly failing to pay off his bills.

New York officials have filed a demand against Swiss Beatz, real name Kasseem Dean, seeking $98,246 (£61,403) in unpaid taxes from 2010.

According to Tmz.com, Alicia Keys' husband also owes $2.6 million (£1.6 million) to the Internal Revenue Service for federal tax debts.

In 2010, Swizz Beatz was hit with a $652,727 (£435,151) lien for delinquent taxes stemming from 2008, but his lawyer insisted he was "negotiating an amicable resolution of the dispute".
