Kate Hudson put on a show by performing Britney Spears’ “. . . Baby One More Time” at talent agency CAA’s pre-Oscar party at Hollywood members club San Vicente Bungalows.

Rumer Willis rocked the party with a version of the Eurythmics’ “Sweet Dreams (Are Made of This)” and “Westworld” star James Marsden and his musician girlfriend Edei performed “Up Where We Belong.” The karaoke kicked off inside the venue’s screening room, with stars getting onstage to sing with the backing of a full band.

Despite pleas from other partygoers, Rami Malek shyly declined to perform “Bohemian Rhapsody,” even though he won a Best Actor Oscar in 2019 for his performance as Freddie Mercury in the movie of the same name, a source told Page Six.

Meanwhile, downstairs at the club’s patio and garden, stars including Tom Cruise, Salma Hayek, Ava DuVernay, Jeremy Renner, Natalie Portman, Margot Robbie, Al Pacino, Jennifer Lopez with Alex Rodriguez, Dwyane Wade, Eiza González, Sacha Baron Cohen and Olivia Wilde were treated to a performance by Swedish pop star Lykke Li.
