History: This adorable friendship actually started with the help of Vogue and Twitter. Taylor mentioned in her 2012 Vogue cover story that she wanted to bake cookies with Karlie, and Karlie responded on Twitter: "You kitchen or mine?" Since then, the two met at the Victoria's Secret fashion show and even went on a road trip to Big Sur.
Current Standing: There was a lot of speculation that the two were a couple when they were spotted allegedly locking lips at the end of last year. It's hard to tell, but we're pretty sure they're just friends. Especially since they just competed to see who is the "best best friend" between them.
