The A-lister looked stunning in a simple head-to-toe black number.
Oozing sophistication, Jessica teamed a simple black top with an A-line skirt and fabulous Bionda Castana heels.
The 32-year old proved black doesn't have to be boring, showing a flash of her toned tum to spice things up.
Jessica threw on a leather jacket over her chic ensemble to keep the chill away and kept her accessories minimal with a simple black clutch.
The US star was flying solo at the event, leaving hubby Justin Timberlake at home. Boo!
But Jess did cosy up with her gorgeous co-star Kaya Scodelario, who looked equally chic in a monochrome dress and statement red lippy.
The beautiful brunette kept her shiny locks loose with a simple wave and went for an eau natural look, with pink lippy and subtle eye make-up.
Looking good, Jess!
