Katy Perry concert postponed until Aug. 21 due to illness

Tonight’s Katy Perry concert has been postponed, promoters announced this morning.

The Friday concert at the Allstate Arena, as well as a concert tomorrow night in St. Paul, Minn., were pulled because of “an attack of food poisoning leading to severe dehydration,” according to Jam Productions.

The Chicago-area concert has been rescheduled to Aug. 21 at the Allstate Arena. Tickets for tonight’s show will be honored, or refunds are available at point of purchase.

“I apologize to my fans in Chicago and the Twin Cities for not being able to perform this weekend,” Perry said in a statement Friday, “but I am going to return in a few weeks to give them the very best show ever!”
