R. Kelly avoided arrest Thursday by showing up in court, but the judge presiding over his child pornography case in Chicago said he'll consider revoking the singer's bond despite his excuse: that police made him late.

Judge Vincent Gaughan said he was "very disappointed" that Kelly, in the midst of a concert tour, failed to show up for a scheduled Wednesday appearance.

Kelly attorney Ed Genson explained his client was tardy because police who pulled over his bus in Utah discovered the log book didn't document enough rest for the driver and ordered it stopped for eight hours.
