Prosecutors in the federal case against R. Kelly dropped a bombshell in court yesterday, accusing R Kelly of sexually abusing underage teen boys.

According to documents seen by TMZ, Kelly met a 17-year-old boy at a Chicago McDonald's in 2006 and invited him and his parents to his home under the guise of helping him with his career.  The next time the teen came over by himself and Kelly began sexually abusing him.  The boy then introduced his 16-year-old male friend to Kelly, and Kelly tried to sexually abuse him too.

The relationship between Kelly and the second boy didn't become sexual until a few years later when he was of age.  In addition to having relations with Kelly, Kelly would watch him have sex with females.

The Fed's new filing also includes new allegations of abuse against and trafficking of underage girls.

In July of 2019, Kelly was arrested by the FBI on  charges alleging sex crimes, human trafficking, child pornography, racketeering, and obstruction of justice.

His trial is expected to start in four weeks.
