A video has emerged that allegedly shows Justin Bieber involved in a fist-fight.

The camera footage appears to show the Sorry hitmaker engaged in a physical confrontation outside of his hotel in downtown Cleveland with a man who is considerably bigger than himself.

It appears from the footage, released by the gossip website TMZ, that Bieber takes a knock to the head before he allegedly launches a blow of his own.

Plenty of people can be seen watching the fight and some even try to step in between the two warring camps, as it ends with them on the floor.

It is not known what or who started the scuffle.
