Justin Bieber has been involved in a clash with a photographer outside a London hotel.
The singer was restrained by a minder as he was seen to lunge at a cameraman after stepping out of a people-carrier.
Bieber is due to perform at the O2 later, despite receiving hospital treatment after collapsing on stage last night.
