is writing his autobiography.
The Smashing Pumpkins
frontman has promised to give a truthful account of his life in the band - of which he is the only remaining original member - including addressing the tensions between himself and former bandmates D'Arcy Wretzky
, James Iha
and Jimmy Chamberlin
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.
Billy also branded former guitarist James a "piece of sh-t
" but insisted he has no resentment towards D'Arcy or Jimmy, even though the drummer released a damning statement when he quit the group for the second time in 2009.
He added to NME
magazine: "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 sh-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.
