Green Day’s Billie Joe Armstrong is angry, you wouldn’t like Billie Joe Armstrong when he’s angry!

Last night at the iHeartRadio festival in Las Vegas, Armstrong threw a profanity-filled tantrum after being told his set would be cut short.

The Green Day front man lost it when his band was cut short by 20 minutes to make more time for mainstream acts like Usher.

When Armstrong realized producers had cut down his time to only one more minute, the singer stopped his performance mid-song and went totally berserk!

“You’re going to give me one minute? One f*cking minute?” Armstrong yelled. “I’ve been around since f*cking 198 f*cking 8 and you’re going to give me one f*cking minute?”

He then made the ultimate statement, “I’m not f*cking Justin Bieber, you motherf*ckers.”

Armstrong dropped the F-bomb a whopping 20 times before using his last minute to smash his guitar on stage.

UPDATE:

Billie Joe Armstrong has entered Rehab for substance abuse following his on-stage meltdown!

A rep for the band released a statement saying:

“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. ”

It is still unknown what substances Armstrong is seeking treatment for.
