Uncle Sam is looking to collect a huge sum of money from Mary J. Blige. According to court documents obtained by the Daily Mail, the 46-year old 9-time Grammy Award winning singer owes the federal government $6.5 million in back taxes, for the years 2008 through 2016. The figure was revealed in an Income and Expense Declaration, filed by Blige on August 8, in Los Angeles. The declaration is a part of the "Real Love" hit maker's divorce proceedings from Martin Isaacs. Blige listed her monthly income at $326,930. In June she was ordered to pay Isaacs $30,000 a month in temporary spousal support. In addition, the singer must cough up retroactive spousal support dating back to September of 2016, plus Isaacs' attorney fees. That total comes to $235,000. Blige filed for divorce in July of 2016, after 13 years of marriage, citing "irreconcilable differences."
