For the first time, Green Day’s Billie Joe Armstrong will talk about his problems with alcohol and prescription drug abuse. In a new cover story for Rolling Stone, the singer discussed the events that sent him to rehab last September and cancelled his band's 2012 tour.

In a teaser for the interview, the punk rock leader told RS his problems would lead to memory lapses. "I couldn't predict where I was going to end up at the end of the night," he admitted. "I'd wake up in a strange house on a couch. I wouldn't remember how. It was a complete blackout."

The wake-up call to get help came after Armstrong's meltdown at the iHeartRadio Music Festival—a night he hardly recalls. "I remember tiny things," he said. "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.’"

The issue hits stands Friday—we hope it has a happy ending!
