Talk about sexy!
Dressed in a beautiful deep red velvet gown by Riccardo Tisci of Givenchy, with one long sleeve and a scandalous thigh-high slit, the 54-year-old actress looked drop dead gorgeous. The dress also featured an oxblood snakeskin leather bodice, which peaked out from under the lush fabric.
The creative director of the French luxury label shared a snap of the "Still Alice" star via Instagram, with the caption, "The Red Queen on the Red Carpet."
The Academy Award winner kept her signature red locks down in a sleek, straight style with a centre part, and accessorized with bold diamond earrings and diamond rings, as well as matching platform sandals. A swipe of vampy red lipstick finished off the look.
She's totally owning it!
