Brie, nominated for Room, went all out for the star-studded ceremony in a bold blue gown with dramatic ruffled skirt and train, which was nipped in at her tiny waist with a sparkling belt.

The 26-year-old clipped her hair back with a diamante pin and added pearl earrings, lots of mascara and a generous slick of bright pink lipstick.
