First came Billie Joe Armstrong's rant, and now comes rehab.
The Green Day singer lost it at the end of the band's iHeartRadio Festival set Friday in Las Vegas, launching into a profanity-filled tirade when he thought their set was being cut short. (It wasn't.)
After, ahem, clarifying with the audience that he wasn't Justin Bieber -- we're guessing there wasn't much doubt in the first place, especially as the Biebs wasn't on the bill -- Armstrong smashed his guitar and hurled the remnants out into the audience.
The band posted an announcement on its Facebook page Sunday: "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."
