The Smashing Pumpkins frontman, Billy Corgan, is writing his autobiography.

Corgan has promised to give a truthful account of his life in the band, and explained that he will be addressing the tensions between himself and former bandmates D'Arcy Wretzky, James Iha and Jimmy Chamberlin.

Speaking to NME magazine he said: ''I'm about 75 per cent through. It explains some of the dynamic between us more accurately, but even then it's just my take on it.''

He added: ''I'm OK with Jimmy. We don't have a relationship at the moment but I mean, I have no ill will.

''I want to see him do well. James Iha I think Is just a piece of s**t. I think he's one of the worst human beings I've ever met in my life. And D'Arcy, she's sort of, in her own way, sort of an innocent. She's not a bad person.''
