Taylor Swift Celebrates BFF Karlie Kloss' Birthday With Pic of Calvin Harris

Taylor Swift took to Twitter on Monday to wish her bestie Karlie Kloss a happy birthday.

Taylor's boyfriend Calvin Harris is also in the birthday pic, which was taken in the kitchen as Karlie cooked up some food on the stove.

"Some of my best times are with her, laughing in the kitchen," Taylor wrote. "Happy Birthday to the ray of light that is @karliekloss!"

Taylor seemed to actively avoid mentioning the other "ray of light" in her life, who she's currently dating – who also appeared to have no idea this photo was being taken! Seriously, just look at that thousand-yard stare.

Karlie turned 23 on Monday, and the gorgeous Victoria's Secret model celebrated by baking herself a cake, which she documented in a short video on Instagram.

Karlie and Taylor have been BFFs for some time. The dynamic duo appeared on together on the cover of Vogue earlier this year, Karlie appeared in Taylor’s “Bad Blood” music video, and Taylor even worked the runway with Karlie at the Victoria's Secret Fashion Show in 2014.

Check out the video below for a look at some of Taylor's other besties, and how they stack up against the newly-23-year-old model.
