MARY J. BLIGE already owes $900,000 in back taxes to the state of New Jersey.  But that's NOTHING.  Because the IRS just filed a tax lien against her for $3.4 million. They say she didn't pay ANY federal income tax in 2009, 2010 or 2011.  Mary J. is also being sued for defaulting on a $2.2 million loan, and her charity is being sued for not paying back a $250,000 loan.
