It has been dubbed 'Super Saturday' - and Wales fans across the globe are living up to that moniker as they gear up for this afternoon’s Six Nations showdown against France.
A quarter of a million people – roughly a twelfth of Wales’ population - are expected to flood into the Welsh capital on a weekend worth an estimated £15m to the Welsh economy.
And excitement is reaching fever pitch as Wales strive for their third Gram Slam in eight years.
History reveals just how close this game could be, with only three Welsh wins against France since the year 2000 to their 11.
But Wales have notched up 10 Grand Slams to France’s nine,and the Welsh side have edged above their visitors in the world rankings.
Bookmakers are slightly in favour of a Wales win - and it seems fans agree.
Further afield, former England captain Will Carling has publicly predicted a 'well-deserved' win for Wales. Even Hollywood star David Hasselhoff has tweeted his support for Wales along with Welsh girlfriend Hayley Roberts.
Captain Sam Warburton has described this game as the most important of his career. But whether Wales win or lose today, no one can dispute the talent of a side who have thus far secured a Six Nations 2012 clean sweep.
