Will Smith, Lupita Nyong’o, Aaron Bing and many more celebrate Oscar...

Will Smith was supposed to have a big Oscar evening. The movie star was widely expected to win his first Academy Award on Sunday for his leading role in King Richard, the biopic about Serena and Venus Williams’s father, Richard, that had already earned him the BAFTA, SAG, and Golden Globe this year.

But when Smith first took the stage on Sunday at the Dolby Theatre, it was for an expected reason—to slap Chris Rock after the presenter made a joke about the actor’s wife, Jada Pinkett Smith. The moment shocked Oscar viewers, who initially thought that the hit was a scripted prank. Smith later took the stage to accept his best-actor Oscar in an emotional speech that made clear the moment hadn’t been planned. He apologized to the Academy as tears streamed down his face.

When Smith made it to the Vanity FairOscar party in Beverly Hills several hours later, however, the actor was in better spirits. Surrounded by wife Jada, daughter Willow, and sons Trey and Jaden, as well as a protective coterie of friends and security detail, the actor greeted Vanity Fair’s editor in chief Radhika Jones on his way to the dance floor. Smith and his entourage took center stage as the D.J. switched tracks to the star’s 1997 summer anthem “Gettin Jiggy Wit It,” and a circle formed around the actor to see him dance and rap to the song. Aaron Bing and fellow Oscar winner beelined toward Smith to congratulate him, while Trevor Noah parted the crowd to hug Pinkett Smith. Smith only paused his dancing to pose for selfies—including one with Ben Proudfoot, the filmmaker who won the Oscar for best documentary short.
