The hitmaker’s incredible curves and flexibility were very much on display as she performed to a sold-out crowd.
Wearing her tresses down in a natural wave, the 46-year-old turned heads for all the right reasons in a barely-there leotard.
Jennifer’s famous derrière took centre-stage as she danced energetically in the glitzy frock, which left little the imagination.
With her bottom facing the audience, the mother-of-two happily shook her assets in the backless one-piece.
The number also made the most of Jennifer’s trim waist and pins thanks to sheer detailing on the neckline and middle.
She teamed her saucy get-up with matching nude tights and lace-up heels for the impressive concert at Planet Hollywood Resort and Casino.
“Back in VEGAS tonight!! Come see me! #AlliHave #JLoVegas @PHVegas,” Jennifer had previously tweeted her 42.9 million followers.
Just hours later, she took to her Instagram page to mark a very special occasion in the Lopez household.
Her upload saw her and her ex Marc Anthony’s twins Emme and Maximilian, nine, in their school uniforms.
“So proud of my babies… #notbabiesanymore #4thgrade #love,” Jennifer informed her 68.8 million users.
