Who's that girl? Fergie looked ready to save Gotham with her slicked back hair and dramatic dress at tonight's Costume Institute Gala in NYC. Calvin Klein dressed Fergie in the black satin number. The singer got all buddy buddy with Molly Sims in Versace on the red carpet and while we're missing Josh by her side, these two lovely ladies look great together. Are you loving all the looks tonight? Don't forget to vote on all of Fab and Bella's love it or hate it polls.
