Jessica Labrie filed the wrongful termination, wage and breach of contract lawsuit in Los Angeles on Tuesday.
"The allegations are completely unfounded and are being made with malice by a disgruntled former employee," Love's publicist Steve Honig said in a statement released Wednesday.
The suit states Labrie worked as Love's administrative assistant for about a year in 2010 and 2011, but was fired after complaining she was owed thousands in unpaid wages and expenses for business trips. The lawsuit also claims Labrie suffered from headaches, insomnia and other medical conditions as a result of Love's conduct.
Labrie's attorney, Joshua Gruenberg, says Love wanted a hacker to change records to businesses she owned or believed she owned, but Labrie refused.
