Though she's had many, many high-profile relationships over the years, Taylor Swift's friendship with Karlie Kloss has remained a constant in her life.
In fact, the Victoria's Secret model has stated that Taylor has no time for guys these days because she's too busy hanging out with her favorite gal pal.
Taylor and Karlie cover the new issue of Vogue together, and inside the mag, they gush about one another as only Taylie can. ("You look like a fairy butterfly," Taylor tells Karlie at one point.)
But no two best friends can be entirely equal, right? Surely one of them has to be the superior bestie.
In order to get to the bottom of who is the more devoted BFF, Taylor and Karlie faced off in the Best Best Friend game. Naturally, the results were hilarious:
We won't give away the ending, but this thing comes down to the final seconds.
It's looking like Taylor is gonna walk away with an easy victory, but when she and Karlie face off in the final challenge (an intense bout of arm wrestling), the competition heats up, and...well, just watch the video. You won't be disappointed.
When you're done there, check out some highlights from Taylor at the Victoria's Secret Fashion Show in the gallery below to remind yourself that it doesn't really matter who's the better friend. The important thing is that they both look really good in underwear.
