Green Day’s Billie Joe Armstrong checks into rehab after iHeartRadio Festival meltdown

Green Day's Billie Joe Armstrong

Green Day lead singer Billie Joe Armstrong has checked himself into rehab two days after having a meltdown on stage during the band’s performance at the 2012 iHeartRadio Music Festival. The band’s rep tells TMZ, “Green day wants to apologize to those they offended at the iHeartRadio Festival in Las Vegas.”

Armstrong was admitted for “substance abuse,” with no further details about what kind of substance available at this time. “The band regretfully must postpone some of their upcoming promotional appearances,” the rep adds.

During Green Day’s Friday night performance Armstrong launched into a profanity-laden tirade after the band’s set was reportedly cut short (though that fact has since been disputed) in which he famously declared, “I’m not f***ing Justin Bieber, you motherf***ers!” Here is a video clip of the meltdown followed by the full f-bombathon:

Oh, f*** this sh!t. I’m gonna play a f***ing new song. F*** this sh!t. Give me a f***ing break. One minute left. One minute f***ing left. You’re gonna give me one f***ing minute? Look at that f***ing sign right there — one minute. Let me f***ing tell you something, let me tell you something, I’ve been around since f***ing 198-f**king-8. And you’re gonna give me one f***ing minute? You’ve gotta be f***ing kidding me! You’re f***ing kidding me. What the f***! I’m not f***ing Justin Bieber, you motherf***ers. You’ve gotta be f***ing joking. This is a f***ing joke. I got one minute — one minute left. Oh, now I got nothing left. Let me show you what one f***ing minute f***ing means. [smashes guitar] One minute. God f***ing love you all. We’ll be back.
