Our girl Taylor Swift has released a behind-the-scenes video for the making of 'End Game' [featuring Ed Sheeran & Future] -- and we're sort of amazed to discover exactly what lengths she went to in order to keep the track from leaking.
Turns out her backup dancers in the video had to perform WITHOUT EVER HEARING THE MUSIC!
"I commend [my dancers] fully," Taylor says. "Because they've been pretending there's music playing when there's not...They've been like dancing to a click track. It's incredibly hard work."
Check out the whole making-of-video below!
