She may never be a royal, but Lorde will be a manager -- at least if BFF Taylor Swift has anything to say about it. 

Stopping by The Tonight Show on Tuesday, Lorde discussed her friendship with Swift, including the moment when she knew they were going to be BFFs.

She explained that the two were at a pre-Grammys party and a man had been talking to Swift -- with Lorde right there -- for about 10 minutes. Easing out of the conversation, the guy said, "'I'll leave my card, is this your manager?' points at me, no beat passed, and she points at me and is like, 'Yeah,'" Lorde explained.

Prank complete and friendship sealed. Watch Lorde recount the cute story -- plus gush about Shake Shack -- below.
