When it came time for singer Lorde to bid her teenage years a fond farewell, she gathered up ALL of her celebrity pals for the occasion. The guest list was a who's who of A-listers from music, fashion, and Hollywood — and the Instagrams prove that fun was had by all. According to E! News, Lorde's pal, Taylor Swift, threw the party at ZZ's Clam Bar in New York City.

Other guests included Lena Dunham, Tavi Gevinson, Karlie Kloss, Mae Whitman, and Aziz Ansari, who committed a major party faux paus by showing up wearing a similar outfit to the night's host.

A video posted to Instagram certainly confirms all our suspicions: Taylor Swift is a killer party planner. Not that we expected anything less from her.
