AJ McLean recalls helping Aaron Carter check into rehab
In a clip from the upcoming Aaron Carter: The Little Prince of Pop documentary obtained by People, the Backstreet Boys singer - who starred in the boyband alongside Aaron's brother Nick Carter - discussed the time the late popstar called on him for advice. "(In) 2017, Aaron reached out to me, asked me for help. I said, 'Look, if you get on a plane, come out to L.A., I will make sure you get into treatment.' And he showed up. I was shocked, but I was happy, and he checked into a treatment centre in Malibu."
