"It breaks my heart to miss out on this weekend's shows with my friends in Charlotte and Atlanta," Taylor says. "I would never cancel if I thought I was physically able to perform these shows. I am so sorry to the fans, but I look forward to seeing you when we come back through your towns, which we will do."
The Charlotte stop has been rescheduled for November 16, while the Atlanta shows will be moved to October 1 & 2. Taylor will resume her performance schedule July 14 in Montreal, Canada.
Last week, the 21-year-old had to postpone her her July 2 stop in Louisville, Ky. for the same reason. The show, which has been moved to October 11, marked the first time ever in her career that the 'Mean' singer has had to cancel.
"Louisville, I so sorry to have to postpone this show to Oct. 11," Taylor posted on her Twitter page. "This is my first time having to do this. I'm so, so sorry."
