Hollywood actress Jessica Alba joins Gabrielle Union in the revealing "thigh game"....and we love it!

We guess it was a "thigh affair" at the Oscar's Vanity Fair Party.

Actress Jessica Alba 35,  attended the star-studded Vanity Fair Oscar party with her handsome husband Cash Warren in high slit pale blue silk chiffon gown with pleated flowers with cascading ruffles by Ralph & Russo.
