Chicago - Singer R Kelly pleaded not guilty to a slew of new charges Thursday alleging he sexually assaulted a teenage fan who met him at his child pornography trial a decade ago.
The 11-count indictment, unveiled last week, replaces charges filed in February centering on an alleged victim identified as JP.
The new indictment adds more serious charges - four counts of aggravated criminal sexual assault - against the R&B singer involving his alleged conduct with JP, whom prosecutors say was underage when Kelly began a sexual relationship with her.
The singer, 52, whose legal name is Robert Kelly, also still faces separate indictments charging he sexually abused three other women - two of whom were also underage at the time.
The four counts of aggravated criminal sexual assault could carry decades in prison on conviction. Previously, the charges facing Kelly brought the potential of up to seven years in prison but left probation a possibility as well.
