Taylor Swift has long documented the peaks and valleys of her relationships in precise pop detail. Whether it’s recalling a relationship lost in “All Too Well” or lamenting love found in “Lover,” Swift is nothing if not forthcoming. This fact makes her rumored rift with former best friend Karlie Kloss all the more intriguing. Once the closest of pals (a joint Vogue cover!), the two are seemingly now estranged.

With the release of two new bonus tracks off her latest album evermore, Swift has inspired speculation once more about who the songs could be referencing. In the case of “it’s time to go,” signs point to Kloss. Here, a history of Karlie and Taylor: The Way They Were.

The Kaylor friendship began with Swift’s 2012 Vogue cover interview. During the discussion in Prabal Gurung’s studio, she spotted a photo of Kloss and exclaimed, “I love Karlie Kloss. I want to bake cookies with her!”
