It was in 2005. I worked at the DFW airport for TSA. Kelly Clarkson came through my check point. It was dead, she was the only passenger being screened. She was in a hurry. She set off the metal detector because she wore jeans with metal rivets the size of quarters all down the legs. I had to do a pat down on her. I did not even know who she was until one of my co-workers asked for her autograph. That's when I checked the name on her ticket and saw it was Kelly Clarkson. She was not rude, just in a hurry.
