R. Kelly pleads not guilty to sexual assault charges

R. Kelly pleaded not guilty Monday to charges he sexually abused four victims, three of them underage, over a span of a dozen years.

Kelly, clad in a bright orange jail uniform and clasping his hands behind his back, looked on as his attorney, Steven Greenberg, entered the plea on 10 counts of aggravated criminal sexual abuse, The Chicago Tribune reports .

Also Monday, high-profile attorney Michael Avenatti, who earlier this month gave prosecutors a VHS purportedly depicting Kelly having sexual contact with a 14-year-old girl, told reporters he had turned over yet another videotape.

The alleged victim on the new tape is connected to the charges brought Friday against Kelly, Avenatti said, but he did not provide further details.

Kelly isn’t scheduled to return to court on the charges until March 22.

Among the allegations laid out by prosecutors against Kelly: that he solicited an underage girl outside his 2008 criminal trial and later sexually abused her; carried on a yearlong sexual relationship with a girl he had met in 1998 when she was celebrating her 16th birthday; tried to force oral sex on his 24-year-old hairdresser in 2003; and videotaped himself having sex with a young girl at his home in Olympia Fields in the late 1990s.

Prosecutors allege Kelly sexually abused his hairdresser while he was free on bond on then-pending child pornography charges.

In a sensational trial in 2008, six years after he was indicted, Kelly was acquitted of charges alleging he filmed himself having sex with his goddaughter, a girl estimated to have been as young as 13.
