Jennifer Lopez seems to truly believe in the phrase, "Have it, Flaunt it." During the Las Vegas premiere of her film "Parker" the singer once again wowed us in a white Kaufman Franco gown. This time the dress was not just figure hugging but Lopez went a step ahead and seemed to go commando in the outfit.

Not that we are complaining. The 43-year-old looked stunning in the floor length gown that featured a sheer back and side panels which not only revealed her toned figure but also showed that she wasn't wearing any underwear. With her hair in an up do, a hint of lipstick and flawless makeup, Lopez posed confidently on the red carpet and flaunted her famous derriere without a hint of skepticism.

She was accompanied by boyfriend Casper Smart, according to nydailynews.com. Smart was dressed in a fitted black suit and posed with Lopez.

Lopez is said to have related well with her character in the film as she herself was going through a tough time during the filming of "Parker". It was around the same time that she and former husband Marc Antony had called it quits.

"When I was filming this role, I had similar feelings. I had recently decided to divorce and it was hard to get out of bed and go to the set every day. I knew what those feelings were, to feel your world was falling apart," Lopez told NBC Latino.

But Lopez has surely moved on and is glowing these days in the company of Smart.
