This is actually really cute. I love them as besties and in some weird way I feel like I'm part of their squad because...you know...I hung out with Ed Sheeran for like 5 minutes.       Anyway, go behind the scenes of the "End Game" music video shoot! You'll learn that Taylor Swift is SOOO secretive about her new tracks, that even her back up dancers don't get to listen to them during the video shoot...they dance to a tap track. CRAZY!
