Green Day's follow up to 2004's 'American Idiot' is being produced by 'Nevermind' knob twister Butch Vig.
Ex-Garbage singer Shirley Manson told US chat show Last Call With Carson Daly that the former Nirvana and Smashing Pumpkins producer Butch Vig was unable to work on her new album as he was busy working with the California rock stars.
She said: "I don't know, to be honest. We're sort of doing our different things. I'm doing the TV show (Terminator: The Sarah Connor Chronicles), Butch is producing Green Day, so he's busy, so we'll see."
The eighth studio album from Green Day was rumoured for a release sometime this year, however only a side-project by the name of Foxboro Hot Tubs - which features all three Green Day members - released a debut record.
It is as yet unclear what role long-time producer Rob Cavallo will have on the new record.
