Pia Toscano, who had been regarded by Las Vegas oddsmakers as the frontrunner in this year's American Idol competition, was eliminated Thursday following the announcement of the audience vote. The announcement touched off boos from the studio audience and surprised comments from the judges. Idol judge Jennifer Lopez seemed particularly upset by the result. "I'm shocked and angry," she said. "I'm never upset on this show and I never get mad," said judge Randy Jackson. "But this makes me mad." As Toscano departed, the audience came to its feet in a standing ovation.
