R. Kelly has been charged with 10 counts by the Cook County State's Attorney.
Prosecutors hit him with 10 counts of aggravated criminal sexual abuse on Friday morning. A grand jury had convened about a week ago to investigate the alleged sex tape that Michael Avenatti handed over to authorities. TMZ broke the story ... 2 women testified for the grand jury over the last week, including one who provided physical evidence.
Prosecutors said there are 4 victims in the R Kelly sexual abuse case. R Kelly will appear in court Saturday afternoon.
Our sources say as many as a dozen accusers came forward to testify.
As we reported, Avenatti says he uncovered the VHS tape during a months-long investigation into allegations his clients made about Kelly having sex with minors. The tape reportedly shows Kelly having sex with a girl who seems to be 14 -- with both Kelly and the girl referring to her genitals and other body parts as being 14 years old.
It's still unclear when the tape was shot, but Avenatti said he was sure it fell within the statue of limitations.
