(Chicago, IL) -- R. Kelly is being accused of having sex with minors and then paying witnesses off to get rid of the evidence. That's according to prosecutors who said Kelly has a "dark side" that he kept hidden from the world behind his fame. The disgraced R&B singer is on trial in his hometown of Chicago for charges of child pornography and obstruction of justice. This comes nearly two months after he was given a 30-year sentence in New York City on racketeering and sex trafficking charges. Prosecutors allege Kelly's "inner circle" helped the singer cover up his abuse and went to "extraordinary lengths" to do so.
