Taylor Swift and Karlie Kloss Compete to See Who's the "Best Best Friend"

It's been a big week for Taylor Swift, who made up with Kanye West, released a new music video, and landed a Vogue cover with her BFF, Karlie Kloss. To accompany their lovey-dovey spread, the singer and model competed against each other in a video for the magazine called "Who's the Best Best Friend?" They were put through a series of tests including talking at the same time, staring into each others' eyes, and arm wrestling — and you might be surprised at who nabs the title. Watch the video above now, and check out more pictures of Taylor and her bevy of celebrity girlfriends here.
