Swift is best friends with Ed Sheeran. They even had two collaborations on this album with "Everything Has Changed" and "Run". So it doesn't seem like a coincidence that Swift may have given him a little shout-out. Sheeran released his fourth solo album, = (or Equals), in October. There are rumours that Swift will be featured on a remix of his song "The Joker and the Queen" off this album. The best friends have been dropping hints since his album dropped.
