Sunday night's Ariana Grande concert at the Sleep Train Arena has been postponed because of the singer's illness. The new date for the concert is Thursday, Sept. 10.
Staff at the arena had to turn away cars after car full of excited fans who hadn't heard the show had been canceled for the night.
Some say that they won't be able to make the Thursday night show because it is a school night.
Sleep Train asks anyone with tickets to hold on to them for admission to the new concert date.
As of now, the concert scheduled for Sept. 8 at Shoreline Amphitheater in Mountainview will take place as scheduled.
