R Kelly 'owes nearly $1m in unpaid taxes'

R Kelly has failed to pay $837,000 in federal taxes, it has been revealed. 
The 'I Believe I Can Fly' star failed to pay the sum and was faced with a tax lien by the Internal Revenue Service (IRS) filed in the singer's native Chicago, reports The Detroit News. 
The amount is said to be separate from the $1,036,858 tax lien against Kelly which the IRS lifted last month.
Kelly has faced multiple financial troubles in recent months. He was sued last month in LA County Superior Court by his former manager for failure to pay for services rendered. 
He is also currently facing a $2.9m foreclosure suit on his Chicago-area mansion after not paying his mortgage since in June 2010. 
Kelly recently underwent an emergency throat operation which will prevent him from singing "indefinitely", though he has vowed to return to performing in the near future.
