Gigi Hadid's breast popped out on the runway of Milan Fashion Week.
The 20-year-old model - who is dating former One Direction hunk Zayn Malik, 23 - walked for Versace on Friday and shocked fans sitting on the front row when her low-cut dress slipped down and revealed her right boob.
Rather than quickly fix the unfortunate wardrobe malfunction, the stunner marched on, and a source recalled Page Six: "That was even more Gigi than Versace paid for, I bet! They got some bang for their buck with that casting. It was literally the longest runway I have ever seen at a fashion show ever, and she had to walk half of it with her boob out."
Rather than be embarrassed, the blonde beauty laughed off the incident like a pro and said on Twitter afterwards.
