NEW YORK (AP) - It's not exactly the gunfight at the O.K. Corral.

One of Times Square's best-known entertainers is heading to court to protect his trademark.

The Naked Cowboy is suing the Naked Cowgirl.

Robert Burck says Sandy Kane is damaging the brand he built up after more than a decade of strumming his guitar while wearing just briefs and a cowboy hat.

Kane, whose real name is Sandra Brodsky, wears a bikini, cowboy hat and guitar in her role as the Naked Cowgirl.

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

Kane's attorney, Nicholas Barnhorst, says he hasn't seen the suit but that Kane has the right to do what she's doing.
