I'm A Celeb's final four will definitely take on Celebrity Cyclone after storm fears

I'm A Celebrity's four finalists will definitely take on Celebrity Cyclone ahead of Sunday's final.

New footage from the grounds of Gwrych Castle, North Wales has given the biggest indication yet that the celebrities will definitely take on the infamous challenge before the show wraps up at the end of this week.

There had been fears the Celebrity Cyclone wouldn't happen this year due to the poor weather.

Drone pictures and videos show the crew testing the challenge ahead of the celebrities taking it on, when they will be pelted by water, foam and all other manner of things as they try and secure their final meals in camp.

Lights flash all around the castle as the show's crew clamber up the slippy slide as they test out the running of it.

Water can be seen gushing down the slide as the crew try and keep their place on the stars in what has always been one of the best challenges of the series for the viewers at home.

Beach balls and jets of water are flung across the slide as floodlights set all around the Cyclone makes sure the cameras can pick up every single minute of the action. Fire shoots up into the sky at the top and the bottom of the slide.

The footage then cuts away to the castle, where blue and white lights move across its famous walls.

It comes after fans feared the whole series could be cancelled amid more poor weather from Storm Barra, as the show's hosts Ant McPartlin and Declan Donnelly previously joked about the bad weather conditions in Wales.

In an interview last week, Ant said: "There's a slight worry because I think there's more bad weather coming next week, but I think it is just temperatures dropping, maybe a bit of snow, a bit of frost, I think we can cope with that."

And Dec laughed, adding: "You never get this in Australia!"

The show's set had been badly damaged during Storm Arwen last month and the show had to be taken off air for three days, whilst the celebrities were also evacuated from the castle.

However, the show did return and has been able to stay on air since, with the final just three days away.
