Cook County State's Attorney Kim Foxx was planning to hold a news conference on the charges at 2 p.m. Friday.
The charge is considered a Class 2 felony in IL.
His first court date is listed as 8 March, said the Chicago Sun-Times, citing court records.
Singer R Kelly was criminally charged in IL on Friday with multiple counts of sexual abuse, local media reported. He has won multiple Grammys, including for his hit-song, "I Believe I Can Fly".
That came on the heels of attorney Michael Avenatti announcing he had handed over to the State's Attorney's Office a videotape that he said showed Kelly having sex with an underage girl.
The indictment says in at least one instance, the abuse of a minor occurred between 1998 and 1999 but that it clearly fell within the 20-year charging window allowed under IL law.
A jury could not identify the man or the girl in the video without doubt, and Kelly was acquitted. The audio captured with the images suggests the girl is 14-years-old.

It was broadly flat at $1.3032 by 1520 GMT on Friday after jumping up and down on mixed messages about progress in UK-EU talks. May has promised to give parliament a chance to decide what to do about Brexit on February 27 unless she can bring back a deal.
IL prosecutors say they expect to announce charges against singer R. Kelly.
"He would like to be able to continue to write and sing and produce and perform", Greenberg said, adding that Kelly is working on an album.
The indictment accuses Kelly of sexual acts with three children older than 13 but younger than 17. The singer had been his protege, and he wrote and produced her 1994 debut album, "Age Ain't Nothing But A Number". The marriage was swiftly annulled.
Despite the slew of unsettling claims against him, the decorated musician for years has continued to perform and maintain a solid fan base.
Legally and professionally, the walls began closing in on Kelly after the release of a BBC documentary about him past year and the multipart Lifetime documentary "Surviving R. Kelly", which aired last month.
The singer is facing 10 felony counts, after four new victims surfaced, claiming R. Kelly had sex with them when they were under age. The FBI, IRS, and Department of Homeland Security have also launched investigations into the singer, which ABC7Chicago reports the latter is looking into sex trafficking and child exploitation crimes.
