Jennifer Lopez stayed true to her revealing red carpet style, and opted for a white gown for the premiere of her latest venture 'Parker', held in Las Vegas. The forty-two year old looked stunning in the Kaufman Franco gown, which featured strategically placed cuts and showed off skin and JLo's lack of underwear. The backless gown was paired with drop earrings, hair piled into a messy yet chic updo, with a black box clutch. Jennifer also rocked black smoky eyes with pale lips for her sizzling red carpet appearance.
