“Rob already seemed to be in a bad mood as he was leaving ICM [Agency] and when he saw me, he just snapped,” claims an X17 photographer.

“I was just standing there, taking his picture, not saying anything, not getting too close and he just went off. He clenched his fist and got ready to hit me.”

“His friend told him to stop and calmed him down,” added the photographer.
