#GuyGoals: Calvin Harris gave Taylor the sweetest anniversary gift

It's been one whole year since Calvin Harris and Taylor Swift became an item – and Calvin certainly pulled out all the stops for her anniversary gift.

The DJ took to Snapchat yesterday to share a short clip of their day together, and it's just the cutest thing ever.

In the video, Calvin shows us a chocolate cake with the words "1 year" iced onto it and two love hearts.

The 32-year-old can be heard saying, "One year, we got one-year cake!" Cuteeee.

A few hours later, Taylor took to Instagram to show off the gift Calvin got her – and all we can say is wow.

A heart-shaped locket engraved with the date they started their relationship.

It really doesn't get much sweeter than that!
