Will Smith was joined by his wife and children at the Vanity Fair Oscars after party, where he clutched his award and performed one of his hits.
The film star and rapper, 53, was named best actor at the 94th Academy Awards ceremony for his performance as Richard Williams, the father of tennis icons Venus and Serena Williams, in King Richard.
However, the victory has been overshadowed – after Smith stormed the stage and hit host Chris Rock in the face after the comic made a joke about his wife Jada Pinkett Smith’s hair loss.
Arriving at the Wallis Annenberg Centre for the Performing Arts in Beverly Hills for the post-ceremony event, Smith posed with Pinkett Smith, 50, sons Trey, 29, and Jaden, 23, and daughter Willow, 21.
The Fresh Prince of Bel-Air star later took to the dance floor while clutching his Oscar to perform his 1998 hit Gettin’ Jiggy Wit It.
Smith was greeted by stars such as Lupita Nyong’o and Trevor Noah as he arrived at the bash, according to The Hollywood Reporter.
DJ D-Nice shouted Smith out as he danced to his own hits, including 1991’s Summertime, which he recorded with DJ Jazzy Jeff.
Members of the Kardashian-Jenner family also attended.
Kim Kardashian, who was without her boyfriend Pete Davidson, posed in a neon blue body-con Balenciaga gown with a train.
Kendall Jenner, meanwhile, opted for a black gown and wore her hair in a ponytail.
On the red carpet, Kourtney Kardashian posed with her fiance Travis Barker from the rock band Blink-182, both wearing black.
Model Chrissy Teigen walked the red carpet wearing a silver dress, while her husband, singer John Legend, looked stylish in a white suit.
Dame Joan Collins was joined by her husband Percy Gibson and wore a glittering silver gown.
Black Panther star Michael B Jordan also made his red carpet debut with girlfriend Lori Harvey.
Also among the stars at the bash were Bond star Lashana Lynch, Rege-Jean Page of Bridgerton, the band Haim, actress Julia Fox and Coda star Troy Kotsur, who showed off his best supporting actor Oscar for the cameras.
An Oscars viewing party hosted by the Elton John Aids Foundation saw appearances from the singer’s husband, David Furnish, Lady Gaga and Queer Eye star Antoni Porowski.
The event in West Hollywood Park raised 8.6 million US dollars (£6.6 million) and featured a performance from six-time Grammy winner Brandi Carlile.
Sir Elton joined via video call from his rescheduled Farewell Yellow Brick Road tour stop in Nebraska, in the US, and treated the audience to performances of Your Song and Goodbye Yellow Brick Road.
He said: “I’m so grateful to my friends Lady Gaga, Billy Porter and Eric McCormack for joining David in hosting such an incredible evening, and of course Brandi Carlile for bringing down the house with an electrifying performance.
“Most of all, I’m thankful to all who attended and participated to ensure that we can continue our lifesaving work to end Aids.
“I could feel the love and support all the way from Lincoln, Nebraska.”
