Steven Tyler admitted on Monday night that it was drug abuse that led him to fall off the stage and break his shoulder at an Aerosmith concert.
"It's not any news here about my drug use and addictions in the past," he told David Letterman on 'The Late Show.' "A couple years ago, I was [snorting] Lunesta because of some problems with my feet."
"That shows you what kind of a drug addict I was, only the finest for me... I was looking for any excuse to get high."
Tyler fell off the stage in a 2009 concert in South Dakota, breaking his shoulder and requiring stitches in his head. It led to tour date cancellations.
Aerosmith had a number of on-stage incidents in 2010, including a seeming fight with guitarist Joe Perry.
Tyler also admitted that he did a ton of drugs in his past -- "It's not any news here about my drug use and addictions in the past," -- and did expensive cocaine in the 1970's and 80's. In June, the singer opened up about his addiction, band breakup and new sobriety.
He also spoke about his decision to become a judge on 'American Idol': "I figured, what the heck, I'll give it a chance... and plus, I get to sit next to J.Lo."WATCH:
