Courtney Love's Ex-Assistant -- She Asked Me to Hire a Hacker, Forge Legal Docs

One of Courtney Love's former assistants is suing the singer -- claiming Courtney asked her to break the law ... by hiring a computer hacker and counterfeiting legal documents.

The ex-assistant Jessica LaBrie filed the lawsuit in L.A. County Superior Court, claiming Courtney intentionally withheld her salary because Jessica refused to "commit fraudulent, unlawful, and unethical acts."

Jessica doesn't specify why Courtney wanted a hacker, or what kind of legal documents Courtney asked her to forge.

Jessica says she worked for Courtney from June 2010 to July 2011 -- often working in excess of 60 hours a week -- but Courtney only paid her a fraction of her salary.

Jessica says she was eventually forced to resign because Courtney wouldn't compensate her -- and now, she's suing Courtney for failure to pay ... on top of a laundry list of other grievances.

FYI -- Jessica's the same ex-assistant currently shopping a tell-all book about Courtney, tentatively entitled "Get Me a Xanax."

Jessica wants unspecified damages.
