Jennifer Lopez wasn’t content with just one seriously sexy outfit at the Billboard Latin Music Awards last night – so after taking the red carpet by storm in a see through dress, she slipped into another racy ensemble.

The 47-year-old singer and actress wowed in an outrageously raunchy Julien Macdonald gown on arrival, before wowing in an even SEXIER barely there frock backstage.

J.Lo turned heads on Thursday evening in a very similar second dress, this one a metallic silver colour and featuring an incredibly plunging neckline, cut outs around the waist and thigh high split, all of which flaunted her fab figure.

The mother of two wore the risky dress on stage to debut her new Spanish language song, Mírate, which earned her a standing ovation from an audience that included ex husband Marc Anthony, the father of her twins Max and Emme, eight.

Jennifer also accepted two prizes on the night: the Social Artist of the Year Award and the Star Award.

Accepting the Star Award, an emotional Jen said : “To come back to my roots has a significance that goes beyond words. Moments like these are proof of hard work and we are lucky if life blesses us in this way.

“I love you so much. I feel blessed to be part of this creative world and to be able to represent our Latin community. I feel at home. I am humbled to be here in your presence and accept this award.”

She later took to Instagram to thank fans for their support – and show off her eye-catching outfits from the night.

Jennifer to had all eyes on her when she arrived at the awards, as she posed on the red carpet in an outrageously racy Julien Macdonald gown.

The Shades of Blue actress was oozing sass in the dress which featured big cut-out panels on either side revealing her firm tummy and a deep plunge that showed off plenty of cleavage.

And then there was the thigh split that highlighted her enviable legs.

J-Lo was even flashing her nude knickers in the mesh dress, which she teamed with sky high peep toe heels and a black clutch bag.

She had her hair scraped back away from her face in a tight pony tail and looked bronzed and beautiful with smoky eyes and glowing cheeks.

Jen’s stylists for the night, Rob and Mariel, told Billboard they wanted Jennifer’s red carpet look to both surprise and retain the star’s signature style.

“The sexy cut, plunging neckline and open back is something that’s become a signature for Jennifer; sexy, feminine, fearless,” they said.

“However, the dress being black with its intricate outlines is a bit edgier and has more of a “gothic” feel than what you’d expect Jennifer Lopez to wear.

“It feels dark and mysterious, which is pretty opposite from Jen’s vibe. It has a major surprise factor yet is still completely her, which is essentially the goal.

Other guests at the annual event included Eva Longoria who was joined by her husband Jose Baston.

The actress looked angelic in a white pant suit, made up of a gaping jacket and wide leg trousers.

Jennifer’s outfit made quite the change to the look she was spotted in the previous day while filming NBC’s Shades Of Blue.

Dressed in full police uniform, Jennifer is seen giving chase to those on the wrong side of the law, throwing men over the top of car bonnets, slapping handcuffs on them, and brandishing a gun.
