Lawyers for disgraced R &B superstar R. Kelly say the singer was taken to the hospital, alleging he suffered an "overdose" caused by officials at a North Carolina prison where he is currently housed.

R. Kelly was rushed to the hospital last week after an overdose that his attorneys claim was an attempt on his life.

Prison staff gave R. Kelly "an amount of medicine that could have killed him," his lawyer alleged in a federal court filing.
