The extravagant celebration took place at the Beverly Hills estate of Amazon founder Jeff Bezos and his partner Lauren Sánchez.
Guests enjoyed a full James Bond experience, including casino-style poker and roulette tables.
The high-profile guest list featured Oprah Winfrey, Mariah Carey, Tyler Perry, Vin Diesel, Mark Zuckerberg, Adele and Rich Paul.
Beyoncé and Jay-Z were also in attendance.
Bruno Mars performed live as partygoers danced beneath a grand marquee set up on the property grounds.
Although mobile phones were discouraged, a photo booth allowed guests to capture keepsakes from what one insider described as “the party of all parties”.
A Busy Night for the Sussexes
Earlier that evening, the Duke and Duchess of Sussex attended the Baby2Baby Gala at the Pacific Design Centre in West Hollywood.
The pair appeared at the charity event to support tennis legend Serena Williams, who was honoured for her work in children’s welfare and maternal health advocacy.
The two back-to-back appearances capped off a busy night for Harry and Meghan, who have been increasingly visible on Los Angeles’ social circuit.
Recent weeks have seen them courtside at Dodger Stadium for the World Series and visiting film sets, where Meghan has stepped back into acting with a cameo in the upcoming Amazon MGM Studios project Close Personal Friends.
