Green Day Frontman Enters Rehab After On Stage Meltdown [VIDEO]
Green Day's front man Billie Joe Armstrong is entering rehab for substance abuse.
The news comes just two days after Armstrong went ballistic in Vegas during a performance at the iHeart Radio Music Festival. He was videotaped screaming obscenities, slamming Justin Bieber and violently smashing his guitar on-stage.
The band's rep issued this statement: "Green Day wants to apologize to those they offended at the iHeartRadio Festival in Las Vegas."
