Katy Perry Cancels Concerts After Food-Poisoning

The singer has re-scheduled dates in Chicago and St. Paul for next month

When Katy Perry opens her mouth to sing, something beautiful tends to come out. When she opens her mouth to eat? Maybe not so much.

The "Teenage Dream" singer was forced to cancel a pair of concerts for Friday and Saturday after suffering a bout of food poisoning and severe dehydration, according to her official website.

The concerts, which were to occur in Chicago and St. Paul, have been rescheduled for next month. Perry fought through the illness to fire up her Twitter account and announce the new dates on Friday, writing, “Chicago and St. Paul—I’m so sorry to have to postpone today and tomorrow’s shows. But I’ll be back 8/21 (CHI) and 8/23 (St. Paul)!”

Perry noted in a statement, "I am going to return in a few weeks to give them the very best show ever!"

Perry's next concert is scheduled for Regina, Saskatchewan, on Wednesday.
