The pop singer and fashion and beauty entrepreneur arrived fashionably late with her new rapper beau, A$ap Rocky, in an all-black ensemble, which pairs a simple T-shirt with a sheer skirt in a classic fishtail silhouette—a stark contrast to her voluminous Balenciaga outfit at the Met Gala. Echoing the show-stopping Bulgari and Thelma West diamonds that she wore on the red carpet, she accessorises her after-party look with a bejewelled headpiece and sparkling tassels. 

According to Vogue, the party was already in full swing when Rihanna arrived, with a free flow of D’ussé cocktails and Jay-Z's Ace of Spades luxury champagne as well as music by Hank Korsan and later, A$AP Lou. Joining her to party the night away were the biggest names in Hollywood, including the Williams sisters, Teyana Taylor, Lil Nas X, Chance the Rapper, Rosalía, Cara Delevingne, Ella Emhoff, Thomas Doherty, Naomi Osaka, Hunter Schafer, SZA, Lorde and many more. Timothée Chalamet and Rihanna's Oscar-winning ex-boyfriend, Leonardo DiCaprio allegedly made surprise appearances, with partygoers reporting the sighting through Deuxmoi, the Instagram account that has gone viral for its insider celebrity content.
