Jennifer Lopez Backside Dress On Red

She's still got it! She may be 43-years old with a ten year career in show business, but Jennifer Lopez can clearly compete with even the youngest pretender in the style stakes.

 The singer and actress stepped out at a promotional screening of her new film Parker showing off her famous behind in an eye popping Kaufman Franco gown.

The floor length white dress featured a number of strategically placed slits which showed J-Lo had forgone underwear for her night out in Las Vegas on Thursday. (You likey?)
