Taylor Swift and Calvin Harris have broken up, according to multiple sources. The 26-year-old singer and DJ/music producer, 32, had celebrated their one-year anniversary in March, followed shortly after by a romantic tropical vacation together. In April, Swift spoke about their “magical relationship,” while Harris told a radio station that Swift is “fantastic.”

It was the Scottish DJ (real name: Adam Wiles) who reportedly called time on their 15-month relationship.

“Taylor and Adam had no big blowout fight, but the romance just was not there anymore for them. Adam is the one that ended it,” a source revealed to E! News. “It was all done in a very mature fashion. Taylor is pretty upset, but they are still in communication. Taylor was there for Adam with his accident.”

“Taylor's heart was more in it than he was. He started to lose interest over the past few months, but really tried to not just break up,” an insider added.

Harris was involved in a car crash on May 20, and the two were last spotted together the day before arriving back to Los Angeles
