(Courtesy of Kelly Walsh)When TV cameras cut to celebrities at the Emmys, what viewers don't see are the people quietly slipping in and out of rows to make sure the audience looks full at the awards show. Purposefully dressed in dark clothing so they don't stand out, seat fillers on Sunday could find themselves next to stars like Seth Rogen, Scarlett Johansson or Selena Gomez. They just better not take a photo with them.This year, one of those people was Yahoo's Kelly Walsh.
