Hilary Swank -- Boys Don't Cry, But Girls File Lawsuits

Hilary Swank is ready to touch gloves and come out fightin' -- she's filed a lawsuit against a company in Southern California for allegedly using pics of her from "Million Dollar Baby" in their ads ... without her permission.

According to a lawsuit filed last week in L.A. Superior Court, Swank says a company called Robert's Home Audio and Video used pictures of her in their ad campaign without prior consent, a violation of her right of publicity.

The lawsuit does not go in to detail about exactly how the images were used ... but does devote 14 pages to listing her credits and awards. Clearly someone does not have a problem publicizing themselves.
