After the events at iHeart Radio, according to Green Day's website Billie Joe is seeking treatment for substance abuse. They regretfully must postpone some of their upcoming promotional appearances for the new albums. They also apologize on his behalf and claim that their set was not cut short. Which we all know is BS. Usher ran well over his time, and no one did anything about it. Either way I wish the best for Billie and hope he gets the help he needs.
