Watch Taylor Swift & Karlie Kloss Arm-Wrestle In This Best Friends Game

Time to put your game face on.

Prepare for the most beautiful thing you've ever seen: friendship. And, yeah, Taylor Swift and Karlie Kloss don't look too bad either.

The two BFFs share the March cover of Vogue, and in the accompanying story they go on a road trip, bake cookies and wear couture in the desert together. And while the fashion mag had time with them, they got Taylor and Karlie to see who could be the best at being a best friend.

They had a staring contest, a talking contest, a drawing contest and an arm wrestling contest. Watch the video to see who emerges victorious.
