Gigi Hadid was assaulted on Thursday while leaving the Max Mara fashion show in Milan.

The 21-year-old supermodel was grabbed from behind and lifted into the air as she and sister Bella Hadid, 19, walked to their car nearby. Instead of waiting for a bodyguard, Gigi defended herself by elbowing the man in the face as onlookers watched the scene unfold.

Some outlets have identified the attacker as notorious celebrity prankster Vitalii Sediuk ,who did post videos from Milan on his Instagram account.

As reports and photos of the incident surfaced, Gigi took to Twitter to address the distressing encounter.

“…I’m a HUMAN BEING — and had EVERY RIGHT to defend myself,” she tweeted Thursday. “How dare that idiot thinks he has the right to man-handle a complete stranger. He ran quick tho.”

While Gigi and Bella are both in Italy for Milan Fashion Week, it’s clear the assaulter picked the wrong model to mess with. An avid kickboxer, Gigi occasionally shares photos and videos from her grueling workouts.
