It's not exactly the gunfight at the O.K. Corral.

New York City's famous Naked Cowboy is headed to court to protect his trademark from the Naked Cowgirl.

Robert Burck says Sandy Kane is damaging the brand he built through more than a decade of strumming his guitar wearing only briefs and a cowboy hat. He's earned as much as $1,000 a day working Times Square from about 11 a.m. to 2 p.m.

Kane wears a bikini, cowboy hat and guitar in her role as the Naked Cowgirl.

The federal suit filed Wednesday asks the court to keep Kane from doing anything that would violate Burck's trademark.

Kane is a former stripper who's now a fixture of the city comedy scene.

Her attorney says he hasn't seen the lawsuit, but Kane has the right to do what she's doing.
