Jennifer Lopez

To celebrate the conclusion of her co-headling concert tour with Enrique Iglesias, Jennifer Lopez got her party on at Sin City's Pure Nightclub in a sinfully-chic, cobalt-blue Georges Chakra frock that hugged her signature curves in all the right places. A "Jenny from the Block"-like coif, snakeskin clutch, and shimmering Louboutin peep-toes completed her Vegas-approved ensemble. (8/19/2012)
