How Taylor Swift, Calvin Harris celebrated their one-year anniversary

Has it been a year already?

Time sure flies when you're smooching at awards shows and riding pool swans bareback.

On Sunday, Taylor Swift and Calvin Harris celebrated being together for 365 days. Tay shared an Instagram with her followers of what we're thinking is really thoughtful gift from her beau.

The beautiful gold locket has a heart shape and is engraved with the date of their anniversary. So cute!

Calvin also shared part of their special day via social. A Snapchat from the DJ, shared by a Swifty, showed what appears to be a homemade cake with chocolate icing and hearts. In the Snap, we also caught a brief glimpse of an incredibly excited Taylor. These guys are so in love! Thanks again, Ellie Goulding for setting them up.

While we didn't see Calvin's face in the Snapchat, he did let followers know just how he was feeling on the big day.

In a tweet, he compared his mood to a photo of Sylvester Stallone giving a thumbs up next to a rainbow. Doesn't get much better than that.

We're happy that these lovebirds had such a wonderful anniversary, and we wish them many more!
