We never knew Rio was a big England fan, but...
The Rugby World Cup kicks off tonight with, England starting their campaign to get out of the group of death with a clash with Fiji at Twickenham.
Stuart Lancaster will be hoping his captain, Chris Robshaw, along with the rest of the side, can live up to their billing as second favourites behind current Webb Ellis cup holders, New Zealand.
And to get them ready for the tournament, and pumped up to as they look to make it out of a group featuring Wales and Australia, the whole country has united behind them.
From people pretending to know stuff about rugby (i.e us) to everyone sending their support to push the hosts to go all the way again.
Now we've never seen Rio talk about rugby before, but it turns out he is a MASSIVE fan, like a seriously massive fan!
JUST LOOK HOW PUMPED UP HE IS! ARGH!
We're 100% sure that England are going to win the World Cup now and it's all thanks to Rio and his really pumped up video...
