Chicago singer R. Kelly is still public enemy number one. New reports claim prosecutors in Illinois are inching closer and closer to having a grand jury convene on his alleged involvement in sex trafficking.

According to reports, Kells and his team could have some serious legal woes around the corner based on witness testimony.

Law enforcement sources tell us federal prosecutors from the Northern District of Illinois will convene a grand jury later this month and offer up witness testimony detailing how Kelly allegedly bought plane tickets and set up hotel rooms for underage girls. We’re told prosecutors will also present emails and text messages that show the coordination Kelly’s team used to set up the travel. Additionally, physical evidence will be presented … which our sources say will include semen-stained clothing. (TMZ)

According to recent reports, feds and prosecutors in Illinois had focused on finding sex tape footage connected to Kells.

Law enforcement sources tell TMZ … the U.S. Attorney’s Office for the Northern District of Illinois is interviewing parties closely associated with Kelly. We’re told prosecutors have been asking about the possible existence of VHS tapes purportedly showing Kelly having sex with minors.Rumors about an alleged stash of R. Kelly sex tapes have been floating around since Kelly went to trial on child porn charges back in 2008, but it’s never been found … not by law enforcement, anyway. (TMZ)

In March,, Kells hopped on Instagram with a birthday shout-out to his daughter.

Recently, Kells’ legal team couldn’t convince a judge to lower his child support payments.

Kelly’s publicist, Darryll Johnson, said Kelly has no assets to sell, not even his home at Trump Tower, because he rents the condo, and paid rent in advance several years ago. Johnson said he and Kelly’s attorneys are representing him for free. Wednesday’s hearing on the child support payments was sealed to the public, but Kelly’s attorneys confirmed afterward that there would be no change in those payments, and the next hearing has been scheduled for May 8.
