Uma Thurman's Naked Nightmare: Tells Letterman Of "Nipplicious Disaster"

Uma Thurman stopped by the "Late Show with Dave Letterman" Wednesday when talk turned to her nipple. As Dave showed pictures of Uma's past and she told about them (like a photo of her at the Nobel ceremony), Uma let out a yelp when a photo from last October's Fashion Rocks event in London came out. Uma's black dress had gone sheer, leaving her right breast clearly visible. She told Dave how it happened, blaming her lack of a "flash test" on the gaffe, and referred to the outfit as a "nipple-icious disaster," saying, "it was humiliating." Scroll down for the photo Dave showed, or watch the exchange:
