One of the paparazzi's favorite couples has called it a day after a 15-month romance. Sources tell People that Taylor Swift and celebrity Scottish DJ Calvin Harris have split up but are still on good terms. "There was no drama," one source says. "Things just don't work out sometimes." Another insider tells E! Online that Harris, who was injured in a car crash a couple of weeks ago, was the one who ended it. "The romance just was not there anymore for them," the source says. "It was all done in a very mature fashion. Taylor is pretty upset, but they are still in communication." (Johnny Depp and Amber Heard's much messier breakup now involves allegations of blackmail.)
