Jennifer Lopez busts a move in lace-up jeans from 2001 ‘Ain’t It Funny’ music video

Jennifer Lopez is giving us nostalgia served hot!

The pop star, 56, slipped into the exact same jeans she wore in her 2001 “Ain’t It Funny” music video to re-create an “Off Campus” scene with actress Mika Abdalla.

For the cheeky clip — which Lopez posted on social media — she paired the ultra-low-slung lace-up denim with a white cropped turtleneck that made the most of her impressive abs.

“It’s a new Jeneration of party people…🎶,” she captioned the video, giving a nod to lyrics from her 2011 collaboration with Pitbull, “On the Floor.”

One observant X user commented on the singer’s “INSANE” pants and shared a snippet from the “Ain’t It Funny” music video.

Lopez confirmed the fan’s suspicions by replying, “They’re the same ones from that video 😀.”

As for Abdalla, she went with her own throwback-inspired look by pairing a brown backless halter top with baggy jeans and a vintage belt.

The clip began with the 26-year-old standing outside Lopez’s dance studio while mouthing her “Off Campus” co-star Khobe Clarke’s line, “I don’t know her personally, but I’m pretty sure that’s J.Lo.”

Abdalla then made her way inside to find the Grammy nominee rehearsing with her crew.

Lopez turned around and mouthed back, “Oh, my God. Wait. This is me! Now!” which Abdalla’s character, Allie Hayes, squealed in a now-viral scene from Prime Video’s new romantic drama series — while wearing a replica of J.Lo’s iconic 2000 Grammys Versace jungle dress.

“Love this shooooww,” the songstress — who gave the plunging gown a second lap while closing Versace’s spring 2020 runway show in Milan — gushed alongside a clip of the aforementioned scene.

Meanwhile, Abdalla recently described just how much work went into creating the “unreal” garment, telling Betches UK that “five fittings” were involved.
