Takes one to know one. Smashing Pumpkins front man, and self-proclaimed own worst enemy, Billy Corgan believes John Mayer is sabotaging himself, reports Rolling Stone.

"He's trying to destroy his career," judged Corgan, after reading Mayer's incendiary comments in his explosive Playboy interview. "Rather than take a year off or change his musical direction... some part of it is irritating his soul to the point where he's trying to blow it up... Certainly [Mayer is] a talented guy, but empathetically, standing on the sidelines, it's hard to watch someone literally burn their career to the ground -- speaking as somebody who's done it."
