(CNN) YouTube singer Austin Jones has been sentenced to 10 years in prison for asking underage girls to send him sexually explicit videos of themselves to prove that they're fans.

Jones, 26, crooned a capella covers of popular songs and performed on tour nationwide. Most of the fans of the suburban Chicago singer were teenage girls.

In 2017, he was arrested on two counts of production of child pornography. Jones admitted to enticing six underage girls to make pornographic videos of themselves and send them to him, according to a plea agreement . The girls were as young as 14.

He pleaded guilty in February, and on Friday, US. District Judge John Z. Lee sentenced him to 10 years in federal prison.

"Production and receipt of child pornography are extraordinarily serious offenses that threaten the safety of our children and communities," Assistant U.S. Attorney Katherine Neff Welsh said in the government's sentencing memorandum. "Jones' actions took something from his victims and their families that they will never be able to get back."
