R Kelly judge threatens jail term

R Kelly is currently touring the US

R&B singer R Kelly has been threatened with jail by the judge in his child pornography trial in Illinois.

Cook County Judge Vincent Gaughan scolded the singer for missing a pre-trial hearing earlier this week, and said he may revoke the star's bail.

"Mr Kelly, I'm very disappointed," he said. "These are extraordinary things and not to be taken for granted."

The 40-year-old has pleaded not guilty to charges of videotaping sex acts with a teenage girl.

"I need more input about what happens to you if I revoke your bail and stop you from concerts," said Mr Gaughan.

Mr Kelly's lawyer, Ed Genson, told the judge his client had always appeared on time in court before and had adhered to other rules and restrictions that had been set.

"He's not violated your honour's trust," he said.

Earlier this week Mr Kelly, who is touring the US, missed a court appearance after his bus was stopped by police in Utah.

Officers ordered the driver to stop for eight hours after the bus log book failed to document enough rest time for him.

R Kelly's hits include I Believe I Can Fly, Gotham City and Thank God It's Friday.
