Billie Joe Armstrong checks into treatment facility after festival meltdown

The rocker and his bandmates were performing at the iHeart Radio Music Festival on Saturday (22Sep12) when Armstrong took offense to a time warning towards the end of his set, storming offstage after accusing concert organisers of disrespecting him.

He raged, "I'm not f**king Justin Bieber, you motherf**kers! You've gotta be f**king joking. This is a f**king joke."

The video footage of his meltdown has since been posted online.

In a statement released to The Associated Press, the band has apologized for the incident, insisting the set was not cut short by promoters, as has been suggested.

A representative has also confirmed Armstrong is seeking treatment, adding, "The band regretfully must postpone some of their upcoming promotional appearances."

The group's new album, Uno, is released on Tuesday (25Sep12).

Armstrong's treatment news comes just weeks after the trio was forced to scrap a show in Italy after the singer was hospitalized with an undisclosed medical issue on 2 September (12).
