Fresh off a performance at the American Music Awards and the release of The Hunger Games: Mockingjay – Part 1 soundtrack, Lorde was interviewed and performed on Jimmy Fallon last night. She talked about the first time she met Taylor Swift at a Shake Shack in New York, that time she pretended to be Swift’s manager at a Grammys pre-show party, and how she came up with the name Lorde. (Bill O’Reilly — the other guest for the night — looks on suspiciously the whole time.) After the interview, she performed “Yellow Flicker Beat,” which was her second time on The Tonight Show stage after she made her TV debut there with “Royals” last year. Watch the interview and performance below.
