Taylor Swift and Calvin Harris have split.

A source familiar with the situation, but not authorized to speak publicly, confirmed to USA TODAY that Swift, 26, and the Scottish EDM DJ, 32, have broken up.

The pair had been dating for about 15 months. In March, they celebrated their one-year anniversarywith pictures on Instagram of their vacation getaway.

Harris, whose real name is Adam Wiles, recently was injured in a car accident in Los Angeles. He was riding in an SUV en route to the airport to catch a flight to Las Vegas for a May 18 show when it was hit by a Volkswagen Beetle convertible, carrying a group of teens, that crossed the center line.

In a recent interview with Vogue, when Swift appeared on the cover, she said she wasn’t thinking of getting married, and was taking things one day at a time.

“I’m in a magical relationship right now. And of course I want it to be ours, and low-key,” she said. “This is the one thing that’s been mine about my personal life.”
