Swift says that she's been advised by her doctor not to perform because of a bout with bronchitis. Her shows in Atlanta and Charlotte, N.C. have been rescheduled for Oct. 1 and Nov. 16, respectively.
The 21-year-old songstress has found something to pass the time while she's sick, though. "Yeah, there are all sorts of fun things to do while sick and on vocal rest," she tweeted on Thursday. "Like sitting here, popping bubble wrap by myself. #wishiwasontour."
