After Friday’s meltdown during a radio festival performance, all eyes were on Green Day‘s Billie Joe Armstrong. Fans were left guessing as to the real cause of his actions on stage. Was Armstrong  enraged over the decision to cut the band’s performance short or was it something else?

In a statement issued to the press today, the band apologized for the on-stage rant and says that the frontman will seek help.

“Green Day’s Billie Joe Armstrong is seeking treatment for substance abuse.” The statement continues, “The band regretfully must postpone some of their upcoming promotional appearances.”

The postponed “promotional appearances” include Monday’s Red Bull Sound Space webcast, which had been scheduled for 3PM PT.

An outpouring of support can be seen all over the internet.

Props & support to @GreenDay for truthfully explaining what happened. Godspeed & good luck for a speedy recovery. Your fans will wait. :-)
