National Trial Lawyers member Gloria Allred says singer R. Kelly threatened to reveal details of an accuser's sex life in retaliation for a lawsuit accusing him of sexual abuse. The Associated Press reports a person identifying himself as Kelly sent a letter containing the threats to one of Faith Rodgers' attorneys in New York. Rodgers is in the recently aired Lifetime documentary Surviving R. Kelly, which explores years of accusations against the singer. Kelly denies any wrongdoing, and one of his lawyers in Chicago denied the letter's authenticity.
