I'M A Celebrity's famous Celebrity Cyclone course was put through its paces outside Gwrych Castle today.

Members of the crew on the ITV hit, which returns tonight at 9pm, were seen setting it up and putting the course through its paces.
Celebrity Cyclone is usually undertaken in the scorching Australian sun - and the UK version looks a good deal chillier.
In fact, temperatures in the North Wales market town of Abergele, where the show is filmed, are currently hovering around seven degrees C.
That could mean the celebs donning wetsuits rather than the usual attire of skimpy superhero-themed T-shirts and capes.
A giant green and yellow slide was spotted in the grounds of the castle where stars including Vernon Kay and Giovanna Fletcher are filming.
Flashing lights and a huge pile of inflatable balls were also piled up ready for the task ahead of Friday's final episode.
The task sees the stars attempting to grab stars from a slippery hill as they’re blasted with wind, water cannons, foam and balls.
It has been a regular feature since series six in 2006 when Myleene Klass, 42, Jason Donovan, 52, and Matt Willis, 37, christened it.

A TV insider told The Sun last week: “This often took place in the heat of the Australian jungle which meant it could easily be staged outside where it needs huge amounts of space.
“That left fans wondering if building something similar in Gwrych Castle in Wales might be impossible, because of the freezing temperatures and the limited room inside the building and its grounds.
“But it seems producers, who are determined to ensure the British equivalent is just as fun as the one Down under, have found a way to make it happen.”
