Green Day frontman Billie Joe Armstrong has opened up about his years of drug and alcohol abuse, his onstage meltdown last fall in Las Vegas and his rehab stint in a new interview with Rolling Stone that hits newsstands on Friday (March 1st). In an excerpt posted at the magazine's website, Armstrong spoke about the many nights he spent high and/or drunk over the years, saying, "I couldn't predict where I was going to end up at the end of the night. I'd wake up in a strange house on a couch. I wouldn't remember how. It was a complete blackout."

Armstrong's issues came to a head at a festival in Vegas, where he smashed his guitar and screamed obscenities at the promoters for reportedly cutting Green Day's set.

He said that he recalls little of that incident, admitting, "I remember tiny things. The next morning, I woke up. I asked (my wife) Adrienne, 'How bad was it?' She said, 'It's bad.' I called my manager. He said, 'You're getting on a plane, going back to Oakland and going into rehab immediately.'"

Armstrong's entrance into rehab forced the band to cancel numerous tour dates and derailed promotional plans for their trilogy of new album, Uno!, Dos! and Tre!.
The trio will get back on the road next month, starting with a performance at Austin's South By Southwest festival.
