Green Day's Billie Joe Armstrong Seeking Substance Abuse Treatment After iHeartRadio Meltdown

It seemed like things were running smoothly for the first night of the second annual IHeartRadio music festival in Las Vegas. The first four hours alone hosted genre-spanning performances from No Doubt, Jason Aldean, Bon Jovi, Miranda Lambert, Swedish House Mafia, Usher and others, with barely a hot mike or technical difficulty between them for an electronics-heavy show.

But just when penultimate performers Green Day were getting ready to debut new songs from ¡Uno! (out Tuesday and the first of three albums due from the rock trio this fall), a teleprompter visible from the crowd suggested otherwise. "One minute?!" lead singer Billie Joe Armstrong howled. "I'm not Justin Bieber, you motherf*ckers! You gotta be f*ckin' joking. I got one minute, one minute left. Now I got nothing left. Let me show you what one minute f*cking means."

And with that, Armstrong and his bandmates proceeded to smash their guitars for their remaining seconds onstage -- to thunderous applause, no less. "One minute. God f*ckin' rob you all. We'll be back," Armstrong said as they stormed off the stage.

What did he mean by that? Day 2 of IHeartRadio starts tomorrow, and thus far the band's official Twitter page (and label Warner Bros.) have remained mum on the situation. But with an itinerary that was only 25 minutes behind schedule by the time Green Day took the stage at 11:30 pm PT ( originally slated for 11:05), and following longer sets from Usher and Jason Aldean, letting the band play an extra song or two couldn't have hurt.
