The 21-year-old supermodel was strutting her stuff during the Alexandre Vauthier Spring Summer 2018 show when the wardrobe malfunction occurred.
Hadid was wearing a black bustier when it happened.
Bella actually posted the photo later on her Instagram, only to later delete it...
This isn't the first time the model has experienced a similar wardrobe mishap on the catwalk.
At the 2017 Victoria's Secret Fashion Show the younger sister of Gigi Hadid smiled through a minor nip slip when she raised her arms dancing while she sported a silver lace bustier bra top.
