Nirvana fans weren't the only ones horrified last week at the controversial Kurt Cobain 'Guitar Hero 5' video that made its way around the internet. Cobain's widow, Courtney Love said she plans to sue Activision after she too was mortified by the sight of a playable character of her late husband enthusiastically singing Bon Jovi's 'You Give Love a Bad Name,' yelling Flava Flav's signature "Yeeeaah boyyyyy" line and many other songs.

If most just assumed that Activision had the approval of the Cobain estate, Courtney Love is adamant that is not the case. "Yeah, we'll sue Activision," Love wrote on Twitter early Thursday morning. "This is disgusting. But there's a lot more."

"I saw a piece of [Kurt's] avatar on the nightly news. I actually had to vomit," she added. Love goes on to rebut the claim that the Activision deal was made in response to the millions in debt due to forgeries regarding the Cobain estate. She says -- in a mind-numbing series of tweets -- that the case now includes 54 phony Power of Attorney documents and 162 bank accounts with Power of Attorney forgeries.

"Have fun with your avatars, you slimebags," Love continued a short while later. "I rant? F--- off. I have proof, you've simply never bothered to look. So f---ing play your video game."

On Wednesday, Love also tweeted, "For the record, this 'Guitar Hero' s--- is breach of contract on a bully's part and there will be a proper addressing of this and retraction." She then added, "We are going to sue the s--- out of Activision. We being the Trust, the Estate, the LLC, the various LLCs, Cobain Enterprises."

UPDATE: Activision has responded, saying that Love signed an agreement that allows them to use Cobain's likeness for the game.

UPDATE: Dave Grohl and Kris Novoselic have responded as well, saying in a statement, "While we were aware of Kurt's image being used with two Nirvana songs, we didn't know players have the ability to unlock the character. This feature allows the character to be used with any kind of song the player wants. We urge Activision to do the right thing in 're-locking' Kurt's character so that this won't continue in the future ... It's hard to watch an image of Kurt pantomiming other artists' music alongside cartoon characters. Kurt Cobain wrote songs that hold a lot of meaning to people all over the world. We feel he deserves better."
