Calvin Harris called singer Halsey a 'sweetheart' on social media after which fans started linking them up
"Taylor was furious and hated the way he never wanted to attend award shows and big music industry events with her," a source told The Sun newspaper.
"Looking back, some friends do feel like Taylor's team manipulated and orchestrated part of her relationship with Calvin after seeing how public she is with her new guy. It makes sense," the insider said
While they danced together, Taylor was filmed as she turned and kissed Tom on the cheek.
