When Katy Perry opens her mouth, multiple #1 hits come out.
Only recently, something else did, if you know what we mean.
We mean that the Teenage Dream singer was forced to cancel concerts for Friday and Saturday after suffering food poisoning and severe dehydration.
The concerts, which were to occur in Chicago and St. Paul, have been rescheduled. Perry, at the very least, already posted the new dates on Twitter:
"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)! I am going to return in a couple of weeks to give them the very best show ever!"
She hopes to be back in Regina, Saskatchewan, on Wednesday.
Get well soon, Katy!
