Courtney Love is being sued over comments she made on twitter.

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 yesterday (05.01.11) 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.
