Steven Tyler says he wasn't the only Aerosmith member who was abusing drugs in recent years.

In an interview with Rolling Stone, Tyler says he and Joe Perry did drugs together in 2008 after years of sobriety. Aerosmith had been working on a new album, which never developed.

Tyler says Perry was so impaired by snorting prescription pills, he couldn't even play his instrument. Tyler says he was no better _ he couldn't sing.

Perry declined to comment to Rolling Stone and didn't return a request for comment from The Associated Press on Tuesday.

Tyler is now a judge on "American Idol." He's releasing an autobiography, "Does the Noise in My Head Bother You?" next month.

The 63-year-old rocker says he's sober now.
