The “Work” singer, 30, hosted a spectacular afterparty at the Up & Down nightclub with owner Richie Akiva in New York City.
The “Happy” singer arrived first alongside his wife Helen Lasichanh. Elon Musk quickly followed suit with new girlfriend, Grimes, where they made a beeline to the VIP area and “just made out for 30 minutes,” a source tells PEOPLE.
Atlanta star Donald Glover, also known as Childish Gambino, made his entrance as the DJ played his new single “This Is America” where the A-list crowd cheered and Diddy insisted the DJ play it twice, another insider tells PEOPLE.
Diddy, according to the first partygoer, was not the only one wanting to bask in the actor, director and singer’s glow.
Blake Lively and Glover were seen chatting away for 20 minutes and with the source telling PEOPLE they “were deep in conversation.”
The hostess of the hour, Rihanna, made her grand entrance in a silver jeweled low-cut shirt and matching pants a little before 3 a.m. where she made her way to the VIP area and was presented with a rare, and pricey, 9 Liter Salmanazar bottle of Armand de Brignac Rosé champagne.
The Black Panther cast also attended with Michael B. Jordan, Chadwick Boseman, Daniel Kaluuya and Letitia Wright spending time together on the dance floor alongside actresses Tiffany Haddish and Issa Rae, the insider reveals.
Aside from making requests of the DJ, Diddy spent the night partying with Glover and Cassie, while superstar friends Mary J. Blige and Busta Rhymes joined his table.
The rapper certainly had a lot to celebrate as the event also marked the debut of CIROC’s first dark spirit, CIROC VS. Diddy made sure to share the first taste with Haddish and his ladylove, Cassie.
Arriving around the same time was Emma Stone and Justin Theroux. Theroux “danced until the early morning,” the first source adds.

George chose a traditional black tuxedo, allowing his wife to take center stage.
Vogue editor in chief and Condé Nast artistic director Anna Wintour named Amal co-host for this year’s Costume Institute benefit gala, themed “Heavenly Bodies: Fashion and the Catholic Imagination,” along with Rihanna and Donatella Versace.
