Bieb’s got out the car, asking the photog to move and when he didn’t, some sorta scuffle happened. The photog called 911, Justin and Selena Gomez left the scene and an ambulance arrived to examine the photographer (he complained of pain in his upper torso). Cops are still investigating. No word from Bieber’s camp, but early Monday morning, he did tweet:

P.S. Why was Bieber’s shoe off though?
