The R&B singer was found guilty of child pornography in Chicago just months after he was sentenced to three decades in prison for sex trafficking.
According to the New York Times and other outlets, Kelly was convicted on six of 13 criminal charges brought against him, including counts of child pornography and child enticement.
He was acquitted of receiving child pornography and obstruction of justice, but two of his former employees were found not guilty.
Kelly was sentenced to 30 years in prison in June after he was convicted of sex trafficking.
The lack of testimony from the victim made it difficult for the jury to convict Kelly, according to the Times.
During the trial this year, she testified that Kelly told her to lie to a 2002 grand jury and deny her appearance on the tape and their sexual relationship.
Since the 1990's, Kelly has been the center of rumors about his relationships with young girls. Kelly married Aaliyah, an up-and-coming singer who was only 15 at the time, in an illegal ceremony. In Chicago and New York, Kelly was charged with child pornography and sex trafficking at the same time.
