Kelly Osbourne was just rushed to an L.A. hospital after suffering a seizure while taping her show "Fashion Police." An ambulance rushed to the scene and Kelly was taken away by stretcher. People held up white sheets to shield her from the media and a white sheet was covering her entire body, including her face. Kelly was sitting in a chair, shooting the show in front of a full studio audience. Melissa Rivers was sitting next to her, filling in for Giuliana Rancic. Kelly turned to Melissa and said, "I don't feel good," and then she fell out of the chair and started shaking. Melissa then turned Kelly's head to help her. Someone from the audience -- some kind of emergency responder -- then ran up and helped. Kelly came around a few moments later, but her handlers wanted to have her hospitalized anyway. The incident occurred at the E! building on Wilshire Blvd., just before noon. We do not know what triggered the episode. As for her condition, it's unknown.
