He's used to female fans screaming his name.
But Michael Fassbender was reportedly the one raising his voice to a girl in Montreal on Saturday.
A source said the 36-year old Irish actor - who is supposedly dating British Olympian Louise Hazel - was walking with the mystery woman, but as soon as he saw a camera he reportedly 'screamed' at her to keep her distance.
Michael wore black jeans and T-shirt, some Toms shoes, and covered his eyes with some aviator sunglasses; but with her hands on her hips, the blonde-haired girl didn't look too impressed with Michael's words.
Wearing a blue cap and a long plait with a loose black vest, skinny jeans and lace-up, peep-toe heels, she still seemed to follow him off the sidewalk and all the way into another building.
The actor was in Montreal on a day off from filming the latest Marvel installment called X men: Days Of Future's Past where he will be reprising his role of Magneto.
