Taylor and Selena's Sweetest BFF Moments Through the Years

In October 2014, Selena made a collage of pictures with Taylor to congratulate her on the 1989 album release. On Instagram, she wrote, "From hotel room album listening parties, kitchen dance floor album listening parties to driving on the pch, windows down album listening parties. -The best part is we were the only ones there. Each time. So happy, honored and proud to know you and your diaries. @taylorswift #1989 BUY IT!!! -now I'll listen live from drowning in my bed sheets."
