The sultry entertainer shook and wiggled her incredible bum for all its worth during a high-octane closing performance on Sunday.

The 45-year-old singer dazzled on stage in a sexy cut-out leotard held together by gold safety pins, a pair of bum-skimming white shorts and a long white train which she later ditched.

And the star’s skin, like her hair, is still in pristine condition.

As was her toned bum with not a hint of cellulite anywhere.

Buckle up: The star wore a floaty white dress held together by safety pins which showed off her tiny waist and shapely curves

She accentuated her facial features with smoky eyeliner, peach blusher and pearly lip gloss.

The crowd were mesmerised during a 90-minute long set by the musician which followed British Mercedes F1 driver Lewis Hamilton’s win.

The mother-of-two got the audience at the Singapore Airlines Grand Prix bash in Padang in the party mood with newer songs such as First Love and I Luh Ya Papi.

She added some classics from her 15-year repertoire including Jenny From The Block and Waiting For Tonight.

The Latin-American pop icon has been criticised over her sexually charged video for her new song Booty with Australian pop starlet Iggy Azalea. 

Viewers, who helped bring the clip to 11 million hits, were quick to draw comparisons to Nicki Minaj’s recent booty filled video clip, Anaconda.

‘What is this, the a** wars? First Nicki with Anaconda and now JLo and Iggy with Booty! Chill your buns ladies,’ wrote Huoa Xiang.

Marcela Brunn also wasn’t impressed by the raunchy material, remarking: ‘not sexy, very vulgar.’

But there were also plenty of positive comments praising the duo’s hard earned physiques with one admirer writing: ‘I wish I had that body!’

Look at me: All eyes were on the singer's bottom

Regardless of the naysayers, the two A-listers seem to be enjoying the exposure.

Lopez took to her Instagram page on Saturday to give a little shout out to her co-star in the form of a short video.

The snippet featured part of Iggy’s rap from the film clip, with JLo writing the lyric: ‘ the last time the world seen a booty this good… #JLoBootyOnVevo featuring @thenewclassic.’

The song is part of her A.K.A. album, which was released back in June. 

A.K.A. opened to first week US sales of 33,000, the weakest of her storied career, but the raunchy clip for Booty is sure to move units.

The song begins with Lopez showing off her toned legs and bodily curves in a black number.

The gorgeous star owns the spotlight as she writhes about, demonstrating her impressive flexibility and core strength as she performs a number of strenuous moves.

Indeed, if you didn’t know that she’s the mom of six-year-old twins, you wouldn’t believe it.

The Let’s Get Loud hitmaker dons a number of sexy ensembles during the more than four-minute video, changing from a black one-piece into a metallic gold cowl-neck top that plunges all the way down to her belly button.

Meanwhile 24-year-old Azalea does the same in a polka-dotted white swimsuit.

The divas then further flaunt their enviable bodies by gyrating their hips and rubbing their posteriors together.

Directed by Hype Williams, the clip begins with a countdown with the words ‘prepare audience for maximum impact’ – but perhaps no amount of preparation would be enough.
