Singer R. Kelly, could be behind bars until at least Tuesday, if not Wednesday as a result of the slow-moving wheels of bureaucracy.

According to a reliable source, R. Kelly’s lawyers plan on heading to the Child Support Bureau on Monday to figure out exactly how much their client owes in back pay.

Once they do that, they’ll head to the bank, pull out the necessary funds and pay off his bail and child support payments in one shot.

That technically would lift the hold on his bond, but due to the procedure it could take 24 to 48 hours to process the paperwork.

In other words … Kels might be sitting in a jail cell ’til mid-week. Surprisingly, as at 7:30 pm, R. Kelly reportedly failed to post the $100k bond by the cutoff time of 9 PM in Chicago, so he’ll have to spend the night in jail.

As at 2:30 pm, reports came that  until R. Kelly makes bail, he’s being held in a holding pen by himself because the jail doesn’t want him interacting with other inmates for safety reasons.

Kelly’s considered a “high profile individual,” and if he doesn’t bond out tonight he’ll be placed in his own cell.

also obtained video of Joycelyn and Azriel leaving the courthouse.

Neither woman had anything to say about Kelly’s case or their relationship with their parents.

Joycelyn Savage  as at 1:15 pm and Azriel Clary were both in the courtroom for R. Kelly, and were reportedly sitting in the first row reserved for friends and family during his hearing.

The women are allegedly the singer’s “sex slaves,” but both have denied that. They were seen holding hands entering court together.
