The 'Britain's Got Talent' judges had to brave the cold when Cardiff auditions moved outside.
Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams temporarily relocated from the warmth of the audition room to cast their eyes over an eight-person diving team.
A shivering Alesha said: "I'm wearing shorts [under my outfit] I'm prepared".
The team, La Quebrada High Diving Productions, showcased a diving sequence, which culminated in a stunt where one of the team climbed a high tower, set himself on fire and leapt into a water tank.
A source said: "The divers were so brave. It was freezing cold but they never let it get to them. The crowd were buzzing with excitement."
Though the outcome of their routine is unknown, Simon believes he has already found the show's winner in the city.
David tweeted: "Simon thinks we may have found the winner of BGT 2013 in Cardiff today."

However, he also wrote: "Blimey there have been some nutters auditioning for BGT today in Cardiff...!"
The diving team includes Team GB's Peter Waterfield, who was Tom Daley's synchronised partner in 2012, and Blake Aldridge, who has also previously worked with the medal winner.
