The R&B star, whose real name is Robert Sylvester Kelly, has faced claims of sexual abuse against women and teenage girls for decades.
He has never been convicted and has previously denied all the allegations.
The 52-year-old is expected to appear in court in Chicago, where he lives, on 8 March.
According to United States media who have seen court records, there are four alleged victims, who were aged 13 to 16 at the time of their reported assaults.
