Erlinda Elemen filed a wrongful dismissal suit against the 55-year-old actress last year, accusing Stone of insulting her Filipino heritage and religious beliefs before allegedly firing her back in February 2011, reported Daily Star.
Stone previously blasted Elemen's claims and branded the case "frivolous" and now she is hitting back with her own lawsuit.
In her complaint, filed in Los Angeles County Superior Court, the Hollywood star maintains her ex-employee borrowed 7,800 pounds from her in 2010 but only paid back 1,870 pounds.
It's not the only legal battle Stone has brewing with domestic staff.
A former maid sued the actress last month, claiming she was dismissed because she refused to do any heavy lifting after hurting her back.
