Green Day Goes Off & Brings Rock & Roll Back! “I’m Not Justin Bieber!

Rock & Roll just got interesting again as Green Day front man Billie Joe Armstrong went off when they were being forced to end their set at the Iheartradio festival in Las Vegas.

Armstrong gets testy around the 5 minute mark noticing how much time was left and dropped a barrage of "F" bombs in succession. He said maybe they should get Usher back out there.

Then close to the 8 minute mark of the video, he goes off noticing they have 1 minute to finish the set. What does Billie Joe do? He goes old school rock & roll style saying "He is not Justin F'n Bieber" and then proceeds to smash his guitar.

Check out the video above. Total rocker craziness!-DocFB
