Pants on the ground! JLS's Oritse Williams flashes his bottom as he struggles to keep his jeans hitched up on a boys' night out
19:34 GMT, 17 June 2012
It's a fashion trend that is popular among teenage boys who feel it necessary to show their underwear to the world above their very low slung jeans.
And sagging, as the trend is known as, also seems to be a favourite among the JLS boys three of whom went out on the town last night with their jeans slung very low across their hips.
But Orits Williams might want to rethink his attire next time he's out in public – or be a lot more careful when getting into a cab.
Scroll down for the song inspired by the low-slung fashion…
Larking about: JLS star Orits Williams flashed his T-shirt as he left a London club last night with his jeans slung low across his hips
The pop star was snapped with his bandmates leaving the Rose Club in central London last night wearing his jeans stupidly low so the focus was on his underwear.
But as he climbed inside a cab to take him home, his jeans feel so low that he flashed his whole bottom through his pants as the denim crept dangerously close to his knees.
He then took a seat next to Aston Merrygold who was also wearing his jeans in the sagging fashion.
This could end badly: Orits's jeans crept closer down his legs as he headed into a cab…
… and he ended up flashing his bottom through his pants as he climbed into the car
Both had their belts went round their thighs which couldn't have been very comfortable to sit on.
The fashion inspired civil rights
activist Larry Platt to write a song about it which he performed during
the Atlanta auditions of American Idol in January 2010.
It became a huge internet hit as the footage of his performance went viral and he released it as a single the following month.
That can't be comfortable, boys! Aston and Orits ended up sitting on their belts as the car took them home
And while Aston and Orits tugged at their hipsters all night, bandmates Marvin Hume and Jonathan Gill had the good sense to wear their trousers in the correct way.
The boys were enjoying a night out together before Marvin ties the knot to The Saturdays star Rochelle Wiseman this summer.
JLS, who were among the acts performing for the Queen at the Jubilee concert earlier this month, just announced that they will be joining the line-up at this year's iTunes Festival at the Roundhouse in London.
Digging deep for his change: Aston also wore his trousers in the sagging fashion but his pockets were almost down to his knees
That's more like it! Marvin Humes and Jonathan Gill wore their trousers in a more sensible fashion
The quartet will make their debut at the annual free festival and join acts such as Jack White and One Direction on the bill for the month-long event.
JLS – whose hits include Everybody In Love and She Makes Me Wanna – will take to the stage on September 6.
The shows will be broadcast online and fans can apply for free tickets at www.itunesfestival.com.
