R. Kelly hasn't paid any of his court fees, but he has $27,828 stored in his commissary account

• R. Kelly hasn't paid any of his court fees, but has $27,828.24 in his prison commissary.
• Prosecutors asked a judge to order the funds seized.

R. Kelly has $27,828 in his prison commissary but hasn't paid a cent toward his court fees and fines, according to federal court documents.

New York Federal federal prosecutors on Thursday asked a judge to order the Bureau of Prisons to seize the money from his inmate trust account and cut a check for that amount to the clerk of courts, according to court documents.

Kelly, whose real name is Robert Sylvester Kelly, is serving a 30-year prison sentence after being found guilty in September of racketeering and sex-trafficking charges that stemmed from a decadeslong practice of recruiting and grooming girls and young women for illegal sex.

A restitution hearing is scheduled for next month, at which time New York Federal Judge Ann Donnelly will decide how much Kelly will have to pay to the victims of his crimes.

Outside of restitution, Kelly owes over $140,000 in fees and fines. Donnelly issued a $100,000 fine based on the conviction plus a statutory $40,000 human trafficking penalty.

Attorney Jennifer Bonjean, who represents the disgraced R&B star, argued that Kelly is "pretty close to indigent" as he didn't have a regular source of income and some stations refuse to play his music.

Prosecutors, though, alleged that Kelly had funneled millions of dollars from music royalties through a childhood friend right before his sex-trafficking conviction.

Kelly is serving his sentence at Metropolitan Detention Center in Brooklyn where he has befriended the accused subway shooter Frank James and is reportedly singing behind bars.

Kelly is set to stand trial on additional federal charges of production of child pornography and sexual abuse of minors on August 15 in Chicago. He has pleaded not guilty to the charges.

The trial comes 14 years after he was previously acquitted of 14 child pornography charges in Illinois in 2008.
