The frightening incident occurred moments after Hadid was spotted leaving the Max Mara show with her sister Bella.
Supermodel Gigi Hadid has defended her actions after elbowing a man - who grabbed her on the streets of Milan without permission - in the face.
In the video taken of the incident Gigi can be seen stopping to take photos with fans while heading to a waiting auto, where the prankster appears to be lingering.
'How dare that idiot thinks he has the right to man-handle a complete stranger.
Naturally, Gigi was startled but she reacted quickly with what seemed like a self-defense move and elbowed the guy and set herself free.
Gigi even thanked her boxing coach on twitter and thanked fans for backing her side of the story.
Bella meanwhile appeared to have had time to make a change as she transformed from her earlier ensemble of a chic blue two piece into a tiny black crop top from label Are You Am I.
"Who the f*** are you, you piece of s***", she yelled after him as her security pulled her back and got her to a waiting vehicle. Her ability to take on a kickbutt routine certainly came to good use when a stranger tried to attack Gigi this morning and received a hella beat down instead.
The handsy fella in question is notorious prankster Vitalii Sediuk, who has weirdly made a name for himself by getting physical with celebrities on the red carpet.
He continued: "You can call it a manifest or a protest". At Paris Fashion Week in September 2014, he pushed Kim Kardashian to the ground while she was making her way through a mob of people exiting the Balmain show.
Hadid appeared in ideal form on the Fendi runway several hours later.
