Some stars chose to ditch their glamorous red carpet gowns and change into something a little more practical for the traditional Vanity Fair Party. Jennifer Lopez traded her stunning pale pink Armani for a chic black Gucci gown at the Vanity Fair after party.

Cameron Diaz dazzled photogs in her shimmering Oscar de la Renta gown but chose a one-shoulder cocktail from the Victoria Beckham collection for the Vanity Fair bash

Also attending the Vanity Fair soiree, Diane Kruger went from romantic to red hot. Her cream ruffled Chanel Couture gown was perfect for the red carpet, but the red-hot number from Calvin Klein is better suited for the after party.
