R Kelly has protested his innocence over the charges

On Wednesday, Mr Kelly was prohibited from visiting the shoot in Los Angeles but the judge ruled he was allowed to visit the Black Entertainment Television (BET) awards ceremony in the city.

The Chicago-based singer has not been allowed to leave the city except on a judge's instructions after being indicted on 21 child pornography offences last June. He was freed on bail.

The charges stem from a videotape that allegedly shows Kelly having sex with an underage girl. The 36-year-old singer denies the charges.

Mr Kelly had planned to travel to Los Angeles to shoot a video for his new single from his forthcoming album.

But Cook County Judge Vincent Michael Gaughan said the singer's lawyers had not produced an argument as to why the singer could not record his performance from Chicago using new technology.

'More harm than good'

However, the singer will appear at the BET awards event on 24 June. He is nominated in two categories.

The judge also allowed him to appear at a concert in Dallas raising money for the families of soldiers killed in the war in Iraq.

Judge Gaughan said preventing Mr Kelly from attending the awards show or the charity concert would "do more harm than good".

The singer is currently number one in the UK chart

In court on Wednesday, Mr Kelly's lawyers argued that preventing the singer from travelling was harming his ability to earn a living.

The singer was in court but remained silent.

No date has been set for Mr Kelly's trial. If found guilty, the singer could face 15 years in jail and a fine of $100,000 (�62,500).

Mr Kelly is still a popular music artist. His most recent album, Chocolate Factory, has sold more than 1.7 million copies in the US alone.

His single Ignition is currently the number one song in the UK single chart.
