Lupita Nyong'o has been lying low since winning Best Supporting Actress at the Oscars.
Nyong'o, 31, looked predictably fashionable at Tuesday's event, donning a Giambattista Valli Couture dress, Christian Louboutin shoes and Graziela Gems jewels. She carried a Judith Leiber clutch.
The honoree Instagrammed a close-up of her manicure; she selected a Diana Broussard nail lacquer.
The red carpet lit up when Nyong'o arrived and everyone started screaming her name. Inside the party, she was all smiles while taking pictures with three pals, including two guys and The Walking Dead's Danai Gurira. The ladies stuck by each other's side throughout the night, a source tells E! News.
