R Kelly has pleaded not guilty to 10 counts of aggravated criminal sex abuse against four victims, three of them minors.

The R & B singer stood in a Chicago courtroom wearing an orange jumpsuit as his lawyer entered the plea, days after the 52-year-old turned himself in and was arrested.

The judge maintained his bail at $1 million of which he must pay 10%.

His lawyer, Steve Greenberg, had said on Saturday that Kelly was not as rich as his fame would suggest.

Known for hits like "I Believe I Can Fly," Kelly surrendered to Chicago police Friday night.

His arrest came after a documentary series renewed attention on decades of accusations against the performer, including child pornography, sex with minors, operating a sex cult and sexual battery.

After a dramatic trial he was acquitted in 2008 of charges of child pornography, also in Chicago.

His next court date is set for 22 March.
