Green Day have confirmed that frontman Billie Joe Armstrong has checked into rehab.
A statement on the band's official website, posted on September 23, read: "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 announcement refers to an onstage incident that occured on September 21, when Billie took exception to being told that his band had only one more minute of stage time. The frontman launched into an X-rated rant before smashing his guitar and leaving the stage.
Kerrang! would like to wish Billie all the best at this time.
