The Chicago Sun-Times reports that Cook County prosecutors filed the new charges against Kelly on Thursday May 30th.
Chicago prosecutors charged the singer with aggravated criminal sex assault, criminal sex assault, and aggravated criminal sex abuse, among others.
Among the new charges are four counts of aggravated criminal sexual assault, two counts of criminal sexual assault by force, two counts of aggravated criminal sexual abuse and three counts of aggravated criminal sexual abuse against a victim between the ages of 13 to 16.
The four aggravated criminal sexual assault counts carry maximum terms of 30 years in prison.
Kelly was already facing 10 counts of aggravated sexual abuse involving four women years ago, three of whom were minors when the alleged abuse occurred.
Kelly is scheduled to appear in court to face the allegations on June 6. In February, Kelly was arrested and charged with 10 counts of aggravated criminal sexual abuse against four women.
