Taylor Swift and Calvin Harris celebrate first year as a couple

Taylor Swift and Calvin Harris celebrated their one-year anniversary on March 6 with sweets and jewelry.

The pair celebrated with a homemade "1 Year" cake. This comes as no surprise, considering Swift's love for baking.

Harris posted a Snapchat video of the cake and of Taylor Swift's giddy smile and nod as he said, "One year. We got one-year cake. We got one-year cake. It's one year. Yay."

Swift later posted a picture on her Instagram of what could have been an anniversary gift from Harris. The gift was a gold locket with the date the couple began dating - March 6, 2015 - engraved on the front.

3.6.15 One year down! ❤️
