J.NO! Jennifer Lopez wears drop-midsection pants with tailor-made Strap peeping out the top on set of music video

She’s long been considered a fashion icon.

But Jennifer Lopez appeared to make a rare fashion misstep on Thursday when the 49-year-old singer arrived on the set of her latest music video in a bizarre outfit.

The Jenny From The Block songstress rocked drop-waist trousers with a tailor-made thong peeping out the top.

A belt don’t cost a thing: Jennifer Lopez appeared to make a rare fashion misstep on Thursday when the 49-year-old singer arrived on the set of her latest music video in a bizarre outfit

The skimpy gray underwear appeared to be made of material matching her pants.

The Out Of Sight actress’ underwear were made even more visible by the addition of a white crop top.

Around her neck and wrists were a bevy of heavy gold and silver chains.

The former backup dancer wore her straight blonde tresses loose and with a center part.

Collaborators: Jennifer reteamed with her Dinero cohort, DK Khaled [L], for the new music video

The video is likely for her forthcoming single Limitless, which the pop star performed at the American Music Awards last month.

The song is from J-Lo’s new film, Second Act, which co-stars Vanessa Hudgens.

The I’m Real hitmaker recently teased the new single on her popular Instagram account, captioning a photo of herself with her kids with an advert.

‘You are my sunshine… #limitless #availablethisfriday. #videocomingsoon #secondact’

The sighting comes after the singer told the December issue of InStyle magazine she looks good at her age because ‘I’ve taken care of myself and it shows.’

And Jenny-Lo shared some of her tips: she does not drink caffeine, she avoids alcohol and she gets lots of sleep. Often the siren is in bed by 10 pm.

But even though she weight trains almost every day, she says she still gets pain in the middle of her back.

Lopez also touched on growing up with more curves: ‘In my family, curves were glorified and part of the culture. It was just like, Jennifer has a big butt, and it’s good,’ she said.
