NEW YORK (AP) -- Kara Dioguardi says the two-judge format could be a one-time thing on "American Idol."
Tuesday's show switched things up by allowing only a pair of judges to review a singer because of time constraints. But Dioguardi, the fourth addition to the judges' panel, expects the series will return to normal next week, giving everyone a chance to chime in.
Dioguardi, who was paired with Randy Jackson, says she learned of the format change shortly before the telecast. She says it was a "safety" measure because last week's performance show ran over schedule.
Simon Cowell blamed her and Paula Abdul for talking too much.
Dioguardi jokingly responds that Cowell will never blame himself for "Idol" snafus.
