She may be 43-years old with a ten year career in showbusiness, 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.
With her long brown hair pulled into a loose updo – black eye make-up and pale lipstick added to her striking appearance.
The star is no stranger to revealing gowns and is particularly famous for the striking Versace green and blue number she wore to the Grammy Awards back in 2000.
The covered view: From the front, J-Lo’s gown looked relatively demure, until she turned to the side to show off the saucy slits
That dress was slit at the front down to the waist and showed off the singer’s curvy figure to the maximum.
But on Thursday, J-Lo even managed to outshine reality star Coco who unusually covered up her famous cleavage in a high necked blue psychedelic mini dress and red heels.
The reality star, who was without husband Ice-T, wore her blonde hair in a long haired tousled style as she stepped out on the red carpet.

The eyewitness said: ‘He came out really quickly, with his head down, like he didn’t want to be seen.’
