R. Kelly says that he is enduring "cruel and unusual punishment" by being held in solitary confinement in a Chicago jail.

Kelly's lead defense attorney Steve Greenberg has filed a motion asking a judge to order the Federal Bureau of Prisons to remove the star from solitary and allow him to mix with the other inmates.

KY3 News reports that Greenberg complained to U.S. District Judge Harry Leinenweber that Kelly was being held on the most restrictive floor of the jail. The floor is usually reserved for inmates who have violated the facility's rules, which Kelly hasn't done.

Prison officials say that Kelly's "alleged offense and notoriety" as a reason to keep him in solitary. Kelly has limited access to emails (although he is illiterate), and is only allowed to take a shower three times a week.

Kelly is accused of sexual misconduct in Illinois, Minnesota and New York, in addition to federal charges.
