Taylor Swift and Calvin Harris ‘starting to question if they can make it to next year

American singer/songwriter Taylor Swift and Scottish singer/DJ Calvin Harris’ relationship is apparently going through a rough patch. The Bad Blood hitmaker and the 31-year-old music producer spent a lot of time apart due to her 1989 tour this year.”Calvin and Taylor barely see each other face-to-face at the moment, and they’re starting to question if they can make it to the next year,” an alleged source told Grazia magazine.
