On The Tonight Show on Tuesday (Nov. 25), Lorde told host Jimmy Fallon that her and Taylor bonded over Shake Shack, particularly their "fat-ass milkshakes."

Then she let everyone know Taylor is funny-like, really funny-by telling a story about one time where Swift pretended Lorde was her manager at a GRAMMY party.

"Without missing a beat," Lorde said in regards to Swift telling some guy she was her manager. Lorde even took the guy's card to keep up with the ruse. "All of a sudden I was Taylor Swift's manager. This like tiny, kind of gothy, like hunched person."
