The Hole rocker has become the first celebrity to have legal action launched against her over comments made on social networking sites - including twitter and MySpace - after a lawsuit was filed by fashion designer Dawn Simorangkir.
Bryan Freedman, lawyer for Dawn told the Hollywood reporter: "There has never been anything like this case before."
Courtney, 46, has reportedly accused Dawn of, among other things, pushing drugs, prostitution and having a history of assault and battery.
Posts made by the `Nobody`s Daughter` singer about the designer include: ``She has received a vast amount of money from me over $40,000 dollars and I do not make people famous and get raped too!"
Courtney has launched many social media rants - often using her own bizarre grammar and including long streams of conscious, punctuated with foul language - including missives aimed at her own daughter, Frances Bean, and friend and musical collaborator Billy Corgan of Smashing Pumpkins.
Courtney`s lawyer, James Janowitz , is confident of her present case, however, saying: "We don`t believe there`s any defamation, and even if there were defamatory statements, there was no damage."
Nevertheless, Courtney has vowed to cut herself off from all social media, writing on twitter: "The end. Am shutting down all social media tomorrow first thing, from here on in i have NO Comment, includes Facebook.(sic)"
Courtney is scheduled to appear in Court in Los Angeles on January 18.
