Green Day singer Billie Joe Armstrong went on an obscene tirade after the band's playing time was cut to one minute to make way for Usher at the iHeartRadio festival in Las Vegas, Nevada (video below).
Armstrong went ballistic when he discovered 20 minutes were getting cut from Green Day's set, reports the Daily Mail.
Armstrong said: "You're going to give me one minute? One f*cking minute? I've been around since f*cking ninteen eighty f*cking eight and you're going to give me one f*cking minute? I'm not f*cking Justin Bieber, you motherf*ckers.'
Armstrong said the f-word word more than 20 times in the minute he had left, before his microphone was turned off, then he smashed up his guitar onstage.
