Apparently David Letterman doesn't remember one of Evangeline Lilly's previous visits to the 'Late Show' (weeknights, 11:35PM ET on CBS). But thanks to her wearing a chain-mail dress, he won't be forgetting Evangeline's latest segment anytime soon.

At first, the 'Lost' actress feigned being insulted and threatened to walk off the show, saying, "You don't watch my show and you don't remember my segments? I'm outta here."

Then her attention quickly shifted to the dress she was wearing, the front lined with wiry loops like chain mail. "You wanta feel it?" she asked Dave. Did he ever. His fingers lingered on the material, and Evangeline struggled to wriggle out of his grasp.
