The model joined husband John Legend at the swanky, star-studded bash and blew absolutely everyone away in this flowing frock by Yousef Aljasmi, which boasted a classic high-neck detail and a stunning glitter splashed cape that trailed behind her.
Chrissy - who revealed that she will be having a baby girl - looked like a Grecian goddess in the crisp white number as she cradled her blossoming bump and treated photographers to a series of side-view snaps.
The stunner whipped her locks back into a super-slick style and swapped yesterday's moody burgundy lip for a swipe of nude gloss and a smokey winged eye. Can we get a round of applause for those cheekbones?
Chrissy teamed her show-stopping look with a hexagonal clutch, incredibly pointy talons and stacked silver rings.
The star schmoozed with Lady Gaga, who paid tribute to the late David Bowie in an extravagant ensemble, Ariana Grande, Selena Gomez and Taylor Swift to name but a few celebs at the West Coast event.
