It took a stint in rehab and months out of the spotlight, but Green Day frontman Billie Joe Armstrong is starting to put his life back together after years of substance abuse.
The 41-year-old rocker, who appears in a cover story in this month's Rolling Stone magazine, revealed publicly for the first time what sent him to rehab last year after a public meltdown at the iHeartRadio music festival in Las Vegas.
"I couldn't predict where I was going to end up at the end of the night," he says. "I'd wake up in a strange house on a couch. I wouldn't remember how. It was a complete blackout."
Last September's onstage debacle at the music festival helped shed light on his battles, however. He had smashed his guitar in front of the crowd while shouting obscenities about pop star Justin Bieber.
"I remember tiny things," Armstrong recalls. "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.'"
Two days later, Armstrong checked himself into rehab, which postponed the band's tour dates, as well as sidetracked promotion for their latest album. The band has since announced new tour dates.
