Mark Salling, the actor who played reformed bully Noah “Puck” Puckerman on Fox’s Glee, has entered a guilty plea to child pornography charges as part of a plea bargain that will see him serve between four and seven years in jail. (Salling was previously facing a possible sentence of as much as 20 years.) Salling will be forced to register as a sex offender when he leaves prison, and will face 20 years of supervised release, including periodic checks of any electronic devices for illegal images.
