While there has been debate over whether Orlando actually managed to land the punch, one onlooker is certain contact was made, telling The Mirror: “The punch definitely connected. People saw it. That’s why everyone cheered.”
Neither star has made a statement on the matter, however, Justin has posted a picture of Orlando crying on his Instagram page.
Hours after the incident is thought to have taken place, Justin posted, and then removed, a photo of Orlando’s ex Miranda Kerr online.
It is believed the Aussie model is the reason behind Justin and Orlando's feud after Biebs reportedly got a little too close to her at the 2012 Victoria's Secret show.
Another source has suggested that, prior to the fight, Orlando refused to address the ‘Baby' singer.
