TMZ reports that the Grammy-winning entertainer totaled $20,403.64 for an American Express credit card bill. American Express claims the rhymer hasn't paid up on the monies owed to the company, even after being sent a notice about the amount.
The credit card company filed a lawsuit against Nelly in October, according to the tabloid website. The suit demanded that the 'Country Grammar' star, born Cornell Haynes, Jr., pay back the more than $20,000 and an additional $3,000 in lawyer's fees, which have yet to be paid.
