UFC welterweight Gunnar Nelson might show as much emotion as The Terminator when he's preparing for upcoming fights, but turn on some Justin Bieber music and he'll show you his moves.
The usually stoic Icelander might seem emotionless before and after almost all of his fights, but he has no problem letting loose for a fun spoof music video shoot.
Nelson recently appeared in a video released with his team in Iceland where they do a spoof to the Bieber track 'Sorry'.

Keep an eye out towards the end of the video because even Nelson's father makes an appearance.
It seems Iceland is full of 'Beliebers' at least judging by this music video.
