R. Kelly avoided arrest Thursday by showing up in court, but the judge presiding over his child pornography case 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.

Gaughan admonished the R&B superstar in court anyway, saying he'll decide Friday whether he should revoke Kelly's bond. The Cook County judge also was to set a trial date Friday.

Kelly is in the midst of a prolonged legal fight after prosecutors say he allegedly videotaped sex acts with a teenage girl. He has pleaded not guilty.

Earlier this week, Kelly canceled a scheduled Thursday night show in Minneapolis. He's next scheduled to perform Friday in Chicago, according to the singer's Web site.
