Talk about a jaw-dropping look! Jennifer Lopez stuck to the metallic theme that she kicked off earlier this week on last night’s episode of American Idol, this time taking it up a notch in a sexy gold ensemble. The triple threat sparkledliterallyin a Georges Chakra embellished dress, nude Casadei ankle-strap pumps with a gold heel, and dazzling Swarovski jewelry.

“Tonight’s dress is made of gold sequins and clear rhinestones, and has sheer panels on the side which allows some skin to show,” stylist Mariel Haenn tells InStyle.com exclusively of Lopez’s frock, which is an altered version of the design she wore in her latest fragrance campaign for Glowing Goddess ($49; kohls.com). “This dress was as perfect for the show as it was for the campaign for her new perfume.”

To complement the provocative ensemble, Lopez wore her hair in long tousled waves and kept her makeup fresh and glowing.
