"Oh, it's so sad to think about the good times

You and I, cause baby, now we’ve got bad blood

You know it used to be mad love."

So sang Taylor Swift in her her 2014 hit Bad Blood.

And, as frequently appears to have been the case for the 26-year-old singer, so life has again followed art; on Wednesday it was reported that she and Calvin Harris, the Scottish DJ and her boyfriend of 15 months, had broken up.

USA Today reported that a source familiar with the situation but unable to comment publicly confirmed that the couple had split. Another source told People magazine: “There was no drama. Things just don't work out sometimes."

There was no official word from either of the pair, who had been dating for about 15 months. In March, they celebrated their one-year anniversary with pictures on Instagram of their vacation.

The 32-year-old Harris, whose real name is Adam Wiles, was recently 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 teenagers, that crossed the centre 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 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.”
