Taylor Swift & Calvin Harris Celebrate Their One-Year Anniversary

Taylor Swift kisses Calvin Harris after winning the award for top billboard 200 album for “1989” at the Billboard Music Awards at the MGM Grand Garden Arena on Sunday, May 17, 2015, in Las Vegas.

Taylor Swift and Calvin Harris are keeping things sweet and sentimental on their one-year anniversary.

The happy couple shared a glimpse of their special day (March 6), with Harris posting a video on Snapchat and Swift uploading a picture to Instagram.

Harris’ video shows off what appears to be a homemade chocolate-frosted cake, decorated with hearts and “1 year” written in icing. In the clip, the camera pans from the cake to a smiling Swift.

Meanwhile, Swift’s Instagram update is a picture of a pretty gold locket engraved with the date "3.6.2015" – presumably an anniversary gift from her boyfriend.

“One year down!” she captioned the picture (with a heart emoji, of course).
