Not only did she take home the Oscar for Best Actress, but Natalie Portman has emerged fashion favourite of the Academy Awards 2011.

The Black Swan actress came out on top in our online vote to find the most stunning gown of the night.

The pregnant 29-year-old complimented her burgeoning baby bump with a regal violet silk-chiffon draped Rodarte gown, its off-the-shoulder V-neck sparkling with Swarovski crystals.

She accessorised her dazzling dress with beaded tassel Tiffany earrings and swept-to-the-side tresses. Purple Jimmy Choo open heels rounded off the look perfectly.

Her winning gown was, however, a last minute decision. Having picked out a John Galliano design for the occasion, the actress reconsidered following controversy surrounding the designer only days before the event.

The battle for second place was closely fought, but Helen Mirren's silk grey Vivienne Westwood Couture gown emerged triumphant with 12% of the final vote, only 1% ahead of Nicole Kidman's white embellished Christian Dior creation.
