Rocker Courtney Love is planning to countersue her former lawyer in a bitter defamation battle.

Rhonda Holmes launched the legal spat, claiming her ex-client defamed her in tweets and press interviews and Love was charged with damaging the attorney's reputation.

But now the Hole star is fighting back, and has filed papers in Los Angeles asking a judge for permission to file counterclaims against Holmes for allegedly making "shockingly false and misleading representations" to her daughter Frances Bean Cobain in a 2009 letter.

Love has accused Holmes of legal malpractice, breach of fiduciary duty and interference, claiming her former lawyer was partly responsible for the deterioration of her relationship with the trustees of her late husband Kurt Cobain's estate, which prompted her daughter to file a temporary restraining order against her.

Holmes' lawyer claims the letter Love is referring to was actually written by the rock star.

The two parties are scheduled to meet in court in January (14) when the defamation trial gets underway.

Holmes' attorney tells The Hollywood Reporter, "We view this as an act of desperation."
