Corgan said Mayor is "a talented guy," and it is "hard to watch someone literally burn their career to the ground – speaking as somebody who's done it." In the March issue of Playboy, Mayer, 32, dished dirt on his ex-girlfriend Simpson, 29, by saying she was "crazy" in bed.
But Corgan believes Mayer should have just kept mum. He said: "I think for any person who has celebrity to sort of drop rocks at somebody else's feet like that, there's things you should really just keep your mouths shut on. There's things that should just be left alone."
While Corgan did not reveal if he ever shared a relationship with Simpson, he previously told Rolling Stone that he had feelings for her. He said: "Sometimes people just like being around each other, and good things come out of that. My goal in life is to love whoever I think is worth loving, and I think if people knew her like I knew her, they would love her like I do. It's really simple."
