Despite this being her third Oscar nomination, Adams declared that she was incredibly nervous on the red carpet. Jitters aside, the actress sparkled in a Cartier diamond necklace and a midnight-blue sequined L'Wren Scott gown, which had an unexpected slit up the back.

The Best Supporting Actress winner fearlessly rocked an incredible architectural Marc Bouwer gown adorned with mirrors. Bouwer also designed the dress Leo wore when she collected her Golden Globe in January.

The Oscar presenter chose a statement-making Gucci Premiere gown. The fitted silver bodice provided structured contrast to the cascading train of ostrich feathers – at once both bold and lady-like.

Nothing says red-carpet-ready like elegant black-and-white. The actress went with a simple strapless Armani Privé, and complemented the look with emerald drop earrings, a bouncy ponytail, and her signature bright smile.

Scarlett Johansson

This lacy Dolce & Gabbana proves that a modest silhouette can still be drop-dead sexy — just add some sheerness at the décolletage, a cutout in the back, and, of course, Johansson's fabulous figure.

Although the hottest star of awards season snuck onto the red carpet just a few minutes before the show began, she was impossible to miss in this chic aubergine chiffon gown. Designed by Rodarte, who created all of the costumes for the Black Swan dancers, the dress had the perfect draping to flatter her burgeoning baby bump.
