According to documents seen by TMZ, the singer and reality television personality claims that two women - named as Kimberly Smiley and Lexi Smiley - illegally recorded a private conversation with her.
Rimes claims that she telephoned Kimberly Smiley in March 2012 in an attempt to make peace, but says that she was "repeatedly insulted, taunted and provoked" during their conversation.
She also alleges in the documents that parts of the conversation were taken out of context and then uploaded to the internet in a bid to discredit her, saying that the defendants are fans of her husband Eddie Cibrian's first wife Brandi Glanville.
Rimes has filed both for breach of privacy and violation of a section of the California Penal Code which deals with the illegal recording of confidential communications.
She is seeking "damages and injunctive relief" based on what she describes as the defendants' "blatant violations of California law".
The documents were filed at Los Angeles County Superior Court earlier today (Thursday, August 30) and Rimes has asked for a jury to try the case.
It was confirmed earlier today that Rimes is seeking medical treatment to help relieve "anxiety and stress".
