iHeartGreenDay: Is rehab really necessary for Billie Joe?? (VIDEO)

Is being HONEST in SHOW BIZ really that OFFENSIVE? Green Day lead singer Billie Joe Armstrong is headed to rehab just days before the band is to release the first of 3 new albums (and hours after he threw out multiple F-bombs and his smashed guitar out  into the crowd, at Clear Channel’s iHeartRadio Festival in Las Vegas). Oh! Maybe the rehab is for people addicted to eye liner? He had more eye liner on than Rihanna. That said, the liner really does bring out his beautiful blue-green eyes.

Green Day, along with Usher and Rihanna, was one of the headliners Friday night at the MGM Grand, but Billie Joe cut short a performance of 1994 hit “Basket Case,” hollering that he wanted to play a new song, and then called attention to a digital ticker that said the band had one minute left onstage.

He used that last 60 seconds to vent. It’s ridden with too many expletives to quote directly. “Give me a … break,” Armstrong shouted. “One minute left. One minute … left. You’re gonna give me … one minute? Look at that … sign right there. One minute. Let me … tell you something. Let me tell you something. I’ve been around since … 1980 … 8 and you’re going to give me one … minute? You gotta be … kidding me … I’m not … Justin Bieber.”

Bieber was not on the bill, but Green Day had taken the stage after Bieber mentor Usher had finished his performance. Green Day, according to an on-site report from the Las Vegas Sun, took the stage about 30 minutes late and performed a truncated set. Rihanna was to close the night, and did so after Armstrong smashed his guitar and stormed offstage.

Green Day’s ‘people’ seemed to want to make it perfectly clear that Clear Channel had nothing to do with pulling the plug on the set by releasing this statement: ”Billie Joe is seeking treatment for substance abuse. We would like everyone to know that our set was not cut short by Clear Channel and to apologize to those we offended at the iHeartRadio Festival in Las Vegas.  We regretfully must postpone some of our upcoming promotional appearances.”

The site didn’t elaborate, but they were supposed to appear on Jimmy Kimmel and Ellen, among others. It’s also unknown whether or not this will affect Billie Joe’s role as a ‘mentor’ (ha!) on The Voice.

We’re really not sure what all the fuss is about—Billie Joe’s performance (both the music and the meltdown) were LEGENDARY. iHeartBillyJoe! EVEN Clear Channel loved his antics, tweeting: “WOW!!!! …and the guitar is officially broken,” and ultimately described Green Day’s ‘set’ as “one of the most epic, punk rock sets in recent memory.”

Green Day’s (1^st) new album “¡Uno!” is set to arrive tomorrow—Sept. 25.
