Celebrity couple Taylor Swift and Calvin Harris have reportedly parted ways after 15 months together.

According to People, which first broke the story, the 26-year-old Shake It Off star and the 32-year-old Scottish DJ have ended their relationship.

However, one source said that it was ended amicably, saying: "There was no drama. Things just don't work out sometimes. No one cheated." 

The couple celebrated their first anniversary in March with a tropical getaway, posting multiple pictures to Instagram. In April, Swift shared a video off herself watching Harris's headline slot at the California music festival Coachella in April.

The same month, Swift gushed to US fashion bible Vogue about her "magical" relationship, saying: "I'm just taking things as they come. 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."

Harris was recently forced to cancel a number of gigs after he was involved in a serious car crash in Los Angeles.

Harris, 32, whose real name is Adam Wiles, was a passenger in a Cadillac when the car collided with a Volkswagen Beetle in Coldwater Canyon, near Beverley Hills on May 20.

A statement posted on Harris's Facebook page last week said he was "still recovering" as he pulled out of two Las Vegas shows. He had previously cancelled a performance at the Omnia nightclub in Las Vegas and a headline slot at the Hangout Festival in Alabama following the crash.

Swift has previously been linked to One Direction star Harry Styles, actor Jake Gyllenhaal and Joe Jonas. Harris previously dated Rita Ora.
