Jennifer Hudson performed at the official opening of The Smith Centre for the Performing Arts in Las Vegas, Nevada, on Saturday.

The singer looked sensational wearing a Ralph & Russo Couture gown which nips her in at the waist.

Her black crystal-embellished gown with a lace neckline was teamed with an amazing pair of burnt-orange sea-glass cabochon earrings.

Hot-pink lips and a half-up, half-down hairstyle, completed the gorgeous look.

The one thing that brings this look down is her visible bra.
