The "Gossip Girl" star was attending the Time 100 gala at Manhattan venue Jazz at Lincoln Center, celebrating her inclusion in the magazine's Most Influential List, when snapper Patrick McMullan accidentally trod on the bottom of her blue Zuhair Murad gown, tearing off the chiffon train.
Martha Stewart was the first to notice that the photographer was the culprit, according to New York Magazine. "Patrick!" she said. "Give her back her train!" McMullan then turned around and exclaimed, "Oh, I seem to have stepped on some lady's train!"
