is threatening to sue everyone over the fact that she didn't authorise Kurt Cobain's likeness to be used in
First on her list appear to be makers Activision and ex-Nirvana member Dave Grohl.
Speaking on Twitter she revealed: "[Grohl] was always a bad seed and is still riding the shit while I take bullets. If there's a hell, he's going. I'm not. We are going to sue the shit out of Activision - 'we' being the Trust, the Estate, the LLC, the various LLCs, Cobain Enterprises. For the record, this 'Guitar Hero' shit is breach of contract on a bully's part and there will be a proper addressing of this and retraction."
Activision's vice president Tim Riley reckons she is talking out of her a*se having actually helped design Cobain's likeness for said game:: "Courtney supplied us with photos and videos. She picked the wardrobe and hairstyle, which turned out to be the 'Teen Spirit' look, then we went back and forth over changes - some subtle, some not so subtle. [She wanted a] sort of athletic definition but not overly so."
