Courtney Love has tweeted that she's planning to take legal action over her late husband's likeness in Guitar Hero 5, saying that she never signed away the rights to have Kurt lip-sync to Bon Jovi.

It started when music journalist Everett True, posted the video above, adding (offensive language warning): "Grohl and Love sanctioned this one for the new Guitar Hero. So respect due to Grohl and Love then. Fucking corporate cock-sucking memory-destroying fret-wanking MTV-supporting fame-chasing money-grabbing grave-turning publicity-loving vacuous spoiled jaded cunting rock whores".

Love responded in a series of increasingly-unhinged tweets, before summing up: "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".

It remains to be seen if this'll delay the release of the game. There's been no response yet from Activision, but we've contacted the PR team to try and get comment. We'll update if they respond.
