Jermaine Dupri facing tax troubles

Jermaine Dupri's financial woes have worsened after the hip-hop mogul was hit with an $800,000 tax bill.

The producer/rapper was recently sued over allegations he defaulted on a $4.9 million bank loan, and now he is facing action from IRS officials.

They have served the star with two tax liens, alleging he owes money from 2008, 2010 and 2011, and the total comes to just under $800,000 , according to TMZ.com.
