In a statement to The Associated Press, the band apologized for the incident and added that their set was not cut short by Clear Channel (who hosted the two-day festival).

During Saturday night's performance, Billie Joe cut a song short, saying he wanted to perform something new. He then launched into an expletive-laced rant when he saw that only one minute remained in his set. "I've been around since f*cking 1988. And you're going to give me one f*cking minute? You've gotta be f*cking kidding me. I'm not f*cking Justin Bieber, you mother f*ckers," he shouted before smashing his guitar on stage. Watch the incident above.
