R. Kelly's trial for child pornography allegations and other charges has once again been delayed.

A federal judge pushed the Chicago case into 2021 due to concerns over the ongoing coronavirus pandemic.

The trial was originally set for April this year before being pushed back to October. The 53-year-old disgraced musician is now set to be tried on Sept. 13, 2021.

The date is subject to change still, judge Harry Leinenweber said in a hearing that took place over the phone.
