The 1989 tour may be over, but the birthday tour celebrating Taylor Swift's 26th year was in full swing over the weekend.

The singer was spotted out with beau Calvin Harris on December 13. The theme of the festivities? A very merry holiday. Santa and Mrs. Claus even appear to have made a cameo! (We're wondering if Kris Kringle put Taylor on the naughty or nice list, though. After the "Bad Blood" video, you never know.)
