In a post on her Twitter.com blog on Friday, Perry writes, "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)!"
In a message on her official website, she adds, "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!"
