Richard Madeley and Frankie Bridge will compete in the first trial of the new series of 'I'm A Celebrity... Get Me Out Of Here!'.
The 'Good Morning Britain' host and the former Saturdays singer were voted to take part in the 'Turrets of Terror' challenge and Sunday's (21.11.21) opening episode of this year's competition - which is again taking place in Gwrych Castle in Wales - will see them race to scale two giant towers and hang in the air while they try to capture their own keys.
Ant McPartlin explained to the pair: “Hanging high in the air between the two turrets are two giant keys.
“The first celebrity to make their way to the top and grab their key will win. Each Turret has three floors with stairs leading to the next level. But to get to the next level you need to go through a locked gate.
“On each floor you must retrieve the keys to unlock the three padlocks to open each gate. When you get to the roof, use your lance to hook your key and drag it over to you.
"The first to retrieve their key has won.”
After this year's group of hopefuls met each other, hosts Ant and Dec warned them they were in for a tricky start.
Ant said: “This year is going to be tougher than ever, all the celebrities will face gruelling challenges on their way to the castle to win the keys to the castle.”
'Emmerdale' actor Danny Miller was particularly daunted by the idea of having to get to camp in a helicopter.
He admitted: “The idea of getting in that helicopter terrifies the life out of me.
"The last thing I want to do is be sick all over the celebrities.”
Danny and former 'BBC Breakfast' presenter Louise Minchin are also sent to play a game of 'Plank Wobble' - 213ft in the air.
Louise said: "It’s terrifying.”
Other stars taking part in the ITV series this year include former footballer David Ginola, producer Naughty Boy, DJ Snoochie Shy, former 'Strictly Come Dancing' judge Dame Arlene Phillips, Olympic diver Matty Lee, and Paralympian Kadeena Cox MBE.
