Before she called it quits on the show
, Jennifer Lopez
stunned on "American Idol" in this skin-tight snakeskin sheath dress by Lanvin. Earlier this summer (June), Spice Girl Melanie Brown
was gorgeous in the same grey frock at the launch of the '90s girl group's "Viva Forever" musical
. Both ladies let their curves do the talking, slicking back their hair and opting for simple makeup accented by a smokey eye. But while J.Lo was her usual glam self and piled on the chunky golden accessories, Sporty Spice kept the bling to a minimum -- that is, until you get down to those fierce stilettos!
