Michelle Obama will appear on the Ellen DeGeneres Show for the second time today, via a video chat from a Joining Forces event at the Jacksonville Naval Air Station in Florida. The First Lady was accompanied by a group of girls whose parents are in the military, and she wore a bright orange, pleated dress with a gold pin and light blue pumps for the occasion. It being mid–April, the topic of discussion was obviously prom season, so both Ellen and Michelle shared their prom photos. While Ellen's dress was a plaid nightmare ("That was a tablecloth at one point."), Michelle's was a low-cut gold number with thigh-high slits. "That split was a little high," she admitted. "I don't know if I'd let my kids go out with a split that high, so let's not show this to Malia and Sasha." Of the seating arrangement, Ellen asked: "Were you shopping at Pier 1 or something?" to which Michelle responded, "You've never done the wicker chair shot?"
