Could this be the first shot from Your Highness? JB found it on a personal flickr page (which I’ll not link to in case he gets into trouble), with a comment that it’s Natalie waiting on the outcome of a joust.
I’m not sure it fits the whole warrior character look, although maybe that was tarnished by the Red Sonja comments…or perhaps her character doesn’t start off as a bad ass. In any case, it certainly LOOKS like her. The ear is probably the biggest give away.
