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).
