Calvin Harris & Taylor Swift Split

Harris and Swift’s breakup was confirmed by multiple sources to a number of outlets. According to those close to the couple, there was nothing dramatic about Swift and Harris’ split, and no one had been unfaithful. “There was no drama. Things just don’t work out sometimes,” an insider told People. “No one cheated.”

It was just three months ago that Swift and Harris celebrated their one-year anniversary as a couple and shared snaps on Instagram from their tropical vacation. And, not long ago, Swift was gushing about how happy she was with the state of their relationship. “I’m in a magical relationship right now. And of course I want it to be ours, and low-key … this is the one thing that’s been mine about my personal life,” she told Vogue.

While Swift was apparently still as smitten with the Scottish DJ as ever, Harris (real name Adam Wiles) was no longer as invested in the relationship.

“Adam really liked Taylor, she was not the type of girl he ever dates and he liked that. He liked how innocent Taylor was and that she had a good caring heart. Taylor’s heart was more in it then he was,” a source told E! News. “He started to lose interest over the past few months, but really tried to not just break up.”

The source added, “This all happened last week. 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. It was all done in a very mature fashion. Taylor is pretty upset but they are still in communication.”

Swift and Harris had first sparked dating rumors in March of last year, when they were spotted at a Kenny Chesney concert in Nashville. The two went public with their romance at the Billboard Music Awards last May.

Before Harris, Swift had dated One Direction’s Harry Styles and Jake Gyllenhaal. As for Harris, he had a high-profile relationship with Rita Ora.
