The American Idol judges reacted with shock and outrage when Pia Toscano, who was the frontrunner, was eliminated.
"I am shocked, I am angry," said Jennifer Lopez.
"America is wrong, I dont know what happened with this," said Steven Tyler.
"Nothing makes me mad, but it makes me mad," said Randy Jackson.
Jaws dropped as 22-year-old Toscano, a wedding singer from Queens, New York, got the boot.
Backstage after the show, Lopez was too emotional to talk to reporters.
So what went wrong?
One theory speculates that viewers didn't like her animal print jumpsuit, which Gwen Stefani helped her pick out from her clothing line.
One columnist actually called the outfit "ridiculous."
Stars are taking to Twitter to express their dismay.
Tom Hanks tweeted, "How could America vote Pia off? I may be done for the season!"
Former Idol contestant Jennifer Hudson wrote, "I can not believe they just eliminated Pia! Really?"
Even the Jersey Shore's Snooki is upset; writing, "Pia should have won the whole thing!"
