The silver lining of a Taylor Swift-Calvin Harris split is we'll probably get a lot of new music.

The 26-year-old singer and the DJ and music producer, 32, have broken up, a source confirms to ET. The former couple celebrated their one-year anniversary in March with a sweet cake, a custom locket and plenty of fawning over each other on social media.

Shortly after their anniversary, Swift and Harris celebrated with a romantic tropical vacation together, where the duo once known as "Tayvin" posed for each other's Instagram pics and wrote their names in the sand. (Adam Wiles is Harris' given name.)

In April, Swift gushed about her "magical" relationship to Vogue, saying, "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."

Around the same time, Harris opened up to a radio station about how "fantastic" Swift is.

"She knows when it's time to leave me for a bit on my own. Before the show," he said. "She's super encouraging and she kind of gets her vibe going with other people as well, you know. She can even cheer up my manager, which is an unbelievable feat! So it's fantastic having her around."
