As the grand finale to Nancy Grace's quickstep on Dancing With The Stars, one of Grace's "twins" wriggled itself out of that tight dress for the world to see. The whole situation was hard to watch. Video slightly NSFW.
Though not much of Grace's flesh is caught on screen, two cut-aways to a bored audience and judge Bruno's comment about a "top-heavy" performance that you "couldn't miss" pretty much confirm it. Of course there's also Nancy's expression, which is a combination of humiliation and horror.
