Green Day's Billie Joe Armstrong is headed to a treatment center for substance abuse following his earlier tirade at the iHeartRadio Festival in Las Vegas. In a statement released first to the Associated Press and now on their Facebook page and website, the band reports:

"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. We regretfully must postpone some of our upcoming promotional appearances."

The band is scheduled to release their latest album Uno—part of a three-album set—on Tuesday. To support the upcoming releases, Green Day recently announced a North American tour and just last weekend played an unforgettable warm-up show at New York's Irving Plaza. (Pictures from that show can be seen here.)

But in what now seems like an ominous hint at events to come, Green Day had canceled a concert in Italy earlier this month when Armstrong was rushed to the hospital for undisclosed reasons. He later attributed the visit to throat troubles. It should be noted that he was also arrested for a DUI back in 2003.

Below is the clip of Armstrong's iHeartRadio rant from this weekend that has quickly gone viral—warning the language in it is NSFW. Keep checking back with Fuse for more details as they develop.
