There’s no love lost between bitter exes Billy Corgan and Courtney Love. The Smashing Pumpkins founder worked with the Hole star on several songs for her new album – but now wants nothing to do with her.

Corgan lit into Love in an interview with the new issue of Rolling Stone Magazine — the same one in which he professes his love for alleged girlfriend Jessica Simpson. Billy says if Courtney releases their collaborations- as it appears she will - “it would be a real big problem, because I haven’t given my permission.”

“I have no interest in supporting her in any way, shape or form,” he added. “You can’t throw enough things down the abyss with a person like that.”

The couple split in 2007.
