Green Day's Billie Joe Armstrong is headed to treatment for substance abuse.

Sunday's announcement by the band's representative comes after the rock frontman had a meltdown onstage at the iHeart Radio Music Festival in Las Vegas. In a clip that has gone viral, Armstrong profanely complained that the band's time was being cut short, then smashed his guitar.

In a statement to The Associated Press, the band apologized for the incident and said that their set was not cut short by Clear Channel, the host of the two-day festival.

The Grammy winning band also is cancelling some of its promotional appearances. It is due to release the album "Uno" on Tuesday.
