Billy Corgan to John Mayer: Shut Your Mouth!

Jessica Simpson has taken issue with, and refused to accept an apology regarding John Mayer's recent Playboy interview in which he talked about railing her.

Now Billy Corgan, who has recently been linked to Jessica, is sounding off on the topic as well. "He's trying to destroy his career," Corgan tells Rolling Stone.

"Rather than take a year off or change his musical direction, some part of it is irritating [John Mayer's] soul to the point where he's trying to blow it up."

"Certainly a talented guy, but empathetically, it's hard to watch someone literally burn their career to the ground speaking as somebody who's done it."

Ruin his career by being a douchebag? Interesting theory ...

Billy Corgan has come to the defense of Jessica Simpson.

"For any person who has celebrity to drop rocks at somebody else's feet like that, there’s things you should really just keep your mouths shut on," says Corgan.

"There's things that should just be left alone."

The Smashing Pumpkins rocker, who declined to confirm his relationship status with Simpson, recently told Rolling Stone that she is definitely worthy of love.

"If people knew her like I knew her, they would love her like I do," said Billy, who helped her pen the theme song for The Price of Beauty, which airs March 15.

For her part, Jessica says that despite John's betrayal and d!ck move, she has no trust issues going forward. Everyone can now breathe a huge sigh of relief.
