The South African beauty wowed in a slinky Salvatore Ferragamo backless gown with beautiful crystal gold leaf-embellished shoulders.
Minimal make-up completed the sophisticated look, with her blonde crop styled into a soft fringed 'do.
The bash, which was hosted by Salvatore and Wallis Annenberg, was also attended by Demi Moore, Nicole Richie, Amy Adams and Gwen Stefani.
Raven-haired actress Demi looked toned, happy and healthy as she walked the red carpet in a floor length sparkling gown in midnight blue. Nicole, meanwhile, wore a chiffon floral foor-sweeping number.
Singer Gwen, who has not yet commented on reports that she is pregnant with her third child, looked to be sporting a baby bump that she covered in a sparkling metallic fringed gown.
Her platinum blonde hair had been pulled up into a twisted bun and was paired with her trademark red lips.
She attended the event with husband Gavin Rossdale and the couple were spotted chatting to Demi over dinner.
Also attending the event was Victoria's Secret angel Alessandra Ambrosio, who stunned in a scarlet jumpsuit with a keyhole cut out.
She was joined by fellow model Karolina Kurkova, who wore a black and gold checkerboard dress featuring side zips.
Other guests included Freida Pinto, Jodie Foster and Dita Von Teese.
