Lorde made a pit stop at "The Tonight Show Starring Jimmy Fallon" on Tuesday to perform "Yellow Flicker Beat" from the "Mockingjay - Part 1" soundtrack. During the interview portion of her visit, Lorde spoke to Fallon about her friend -- you may know her! -- Taylor Swift and told the story of how they met (at Shake Shack), and that one time someone thought Lorde was Swift's manager. Swift played along, encouraging the oblivious guy to hand Lorde a business card. These pranksters.
Watch her perform "Yellow Flicker Beat."
