Her website says Perry is suffering from food poisoning, which led to severe dehydration. Oh no!

Perry performed Thursday at Summerfest in Milwaukee, sticking it out through the concert even though she was sick. She received medical attention before and after the performance.

But now, Perry has gotten too sick to sing. She's rescheduled the concerts for Aug. 21 and 23 or offered fans a refund.

Said Katy: "I apologize to my fans in Chicago and the Twin Cities for not being able to perform this weekend. But I am going to return in a few weeks to give them the very best show ever!"

Well-handled, Katy! Hope you feel better!
