Beleaguered rap mogul Marion 'Suge' Knight's money woes continue to mount - U.S. government officials have demanded he pay more than $6 million in unpaid taxes from 1996. The former Death Row Records' boss had a tax lien filed against him in 2003, stating he had not paid the $6,578,696 bill he owed for earnings made seven years earlier.

He failed to hand over the staggering amount, forcing the government to re-file the claim in January this year, according to

It's not the first of Knight's money troubles - he put his Las Vegas property up for sale in August after filing for bankruptcy in 2008.

In February, a collection of his valuables in storage was auctioned off to cover his unpaid storage bills.
