Green Day frontman Billie Joe Armstrong has checked into rehab.
It's unclear why specifically he did so, but the band issued a statement saying he'll be “seeking treatment for substance abuse,” following his epic on-stage rant in Las Vegas Friday night.
Believing Green Day was being cut off prematurely at the iHeartRadio Festival, Billie Joe exploded in an expletive-laden tirade, bashing Justin Bieber and smashing stuff (you gotta see it):
Armstrong’s bandmates said he was mistaken about the gig.
“Green Day would like everyone to know that their set was not cut short by Clear Channel and to apologize to those they offended at the iHeartRadio Festival in Las Vegas,” the statement reads.
