We had no idea!

Alec Baldwin opened up about his battle with alcoholism and drug abuse in a new interview with Good Morning America, set to air this coming Monday, and the actor didn't sugar coat things.

"I got sober when I was just about to turn 27. And those two years that I lived in that white, hot period, as a daily drug abuser, as a daily drinker … to my misery, boy, that was a tough time. There was really, really a lot of pain in there. A lot of pain," he explained while promoting his new memoir Nevertheless.

When interviewer George Stephanopoulos asked the funny man what would have happened if he never got clean, the Boss Baby star revealed that he believed sobriety was always his destiny.

“I think I was one of the people who was lucky that it stuck, and therefore if I didn’t get it then, I think I would’ve got it eventually. I know that at that time, what I describe — overdosing on drugs — which I’ve kept very private for years and years... But, I’m glad I got it when I did ’cause not many people get sober when they’re young," he mused.

Good for him!
