The 'On The Floor' singer led the fash pack at Paris Fashion Week on Sunday (6 July), where she joined Donatella Versace for the Atelier Versace Haute Couture Fall Winter '14 show.
And, never one to shy away from making a statement, Jenny From The Block donned a white floor-length gown with half a sparkly trouser... as you do!
Her fancy frock was designer by Versace (obvs) and featured a strapless neckline plus a rather daring slit running all the way up one side.
But J.Lo opted to flash just one pin, keeping the other covered up with her dazzling sequin-clad trouser leg.
Bizarre? Yep... but it could be pretty useful too - just think how much time you'd save by only having to fake tan one of your pins!
Adding even more glamour to her look, the songstress wore strappy metallic sandals complete with a sky-high platform and towering stiletto heels.
She also sported dramatic gold earrings and an oversized cuff bracelet while slicking her highlighted locks into a sleek high ponytail.
Now this may be one of the strangest frocks we've seen in a long time, but, being J.Lo, she totally managed to pull it off!
