Two names clearly identifiable on the cast include Lorde's bestie, Taylor Swift, and Yeezus - aka Kanye West.
Lorde also told her Instagram followers a little bit about her "magical night" at the Gala.
"We ran through the museum after dark, and danced to Prince, and hugged and kissed," she wrote.
Her big evening ended after 3am.
No doubt it will be back to the grind today for the singer, who is currently in the US working on her new album.
She is reportedly writing songs with Lena Dunham's partner, Jack Antonoff, who recently won a Grammy for his work on Taylor Swift's 1989 album.
