Teylor Swift performed "Night Away Dance" at CAA's pre-Oscars party on Friday night while Tiffany Haddish and Donald Glover had a freestyle rap fight and sang karaoke tunes backed by a live band.
Guests Leonardo DiCaprio, Hailey Bieber, Elon Musk, Sacha Baron Cohen, Al Pacino and Chris Pine also attended the power agency's party at the exclusive San Vicente bungalows.
Sources told Page Six that Swift parted ways with boyfriend Joe Alwyn, as well as Andrew Garfield and Zoe Kravitz.
Haddish — who wore short blond hair, a glamorous black gown and sparkling diamond necklace — enthralled the crowd at the venue's theater with a theatrical rendition of Tina Turner's "Proud Mary."
Glover also sang the tunes before two stars were injured in a freestyle rap battle.
The “Atlanta” star – aka rapper Childish Gambino – hit Haddish with the lines, “And I just don’t care/She’s on stage with the white blond hair,” to which quick-witted comedian Haddish fired back, “And I ain’t got no motherf–kin’ underwear!” according to a clip posted to social media.
Said a source: “Tiffany Haddish and Donald Glover had the theater packed performing karaoke to a live band.”
Also spotted at the CAA party, we hear, were J.J. Abrams, Denis Villeneuve, “Squid Game” star HoYeon Jung, Regé-Jean Page, Trevor Noah, Taika Waititi, Rita Ora, Winnie Harlow, Ron Howard, Gayle King, Savannah Guthrie, Sebastian Stan, Simu Liu, Zooey Deschanel, Jonathan Scott and more.
Meanwhile, Hollywood agency WME opted for a smaller affair this year - an intimate dinner with a few tables at Craig's on Friday nights for the agency's nominees.
Maggie Gyllenhaal, Kristen Stewart, Javier Bardem and “King Richard” director Reynaldo Marcus Green each presided over a table behind the celebrity hot spot, sources said.
Well-wishers included Warner Bros. studio boss Toby Emmerich, James Bond franchise producer Barbara Broccoli, "Don't Look Up" producer Kevin Messick, actress-producer Colleen Camp and WME partner Alice Scherz (who represents Gyllenhaal, Stewart and Bardem).
Detectives said each table had Polaroid cameras for guests to take funny pictures.
