Country star Shania Twain has canceled two of her upcoming tour dates as she battles as respiratory infection.

The You're Still The One singer was slated to bring her Rock This Country tour to Manchester, New Hampshire and Albany, New York on 6 and 7 October (15), but hours before her Manchester stop, it was announced she could not go on as planned due to illness.

"Shania Twain’s doctors have advised her to rest for several days after she was diagnosed with a respiratory infection," a statement on her Facebook page reads.

"The concert dates are unable to be rescheduled due to Shania Twain’s current touring schedule. All tickets will be refunded at point of purchase. Shania Twain apologizes for any inconvenience this may cause her fans and greatly appreciates their understanding."

Twain is scheduled to resume her tour on Friday (09Oct15) in Quebec City, Canada.
