Singer Leann Rimes is suing two women who allegedly recorded a phone call with the star and then went public with what she said on the Internet.
Rimes has checked into a treatment facility to help her cope with stress and anxiety brought on by attacks on her marriage to actor Eddie Cibrian - and now her lawyer has revealed she's planning to go after two of the critics who have made her life a misery.
Larry Stein tells TMZ.com his client has been victimised by a gang of cyber-bullies, explaining, "Leann will take all of the appropriate steps to address the harm that (she) has suffered as a result of this criminal conduct."
TMZ.com has now obtained a copy of her suit, which was filed in Los Angeles on Thursday.
Rimes claims Kimberly and Lexi Smiley engaged in a campaign to trash her when she hooked up with their friend Brandi Glanville's then-husband Cibrian.
The singer claims the Smileys secretly recorded a phone chat she had with Kimberly earlier this year - and then released out-of-context excerpts that made Rimes seem "crazy and delusional".
The singer is suing for invasion of privacy.
