We can't stop watching or laughing at it, it's seriously the best. Even Taylor herself tweeted about the awesome vid. "Just smiled so big as I watched this girl joyously dance-bomb a Whole Foods like a champion," Taylor posted.
In it, a girl named Mackenzie is seen dancing her face off to Tay's new hit song. The best part is that she embarrassingly dances around the serious people of the grocery store. It's freaking hilarious.
Mackenzie reminds us of that one BFF we all have...you know, the no-shamer. She just makes us want to get up and shimmy around everyone we see. Watch below.
