Declan Donnelly said in the clip: “Hello everybody, we’ve got news for you.

“It’s probably the worst kept secret in television but we can confirm we are doing a very special series of I’m A Celebrity… Get Me Out Of Here! in South Africa.

“We’re here, it’s going to be your favourite celebrities from the last 20 years who are going back in to do it one more time in South Africa.”

Ant and Dec then both excitedly shouted out "South Africa!", and went on to confirm that the main series would be taking place in Australia this year.

I'm A Celebrity has been filmed at Gwrych Castle in Wales for the past two years as coronavirus travel restrictions prevented it from being set in Australia as usual.

Former campmates who have been rumoured to be taking part in the All Stars series include Myleene Klass, Carol Vorderman, Andy Whyment, Jordan Banjo and Amir Khan.

Other famous contestants over the years have included Katie Price, Peter Andre, Kerry Katona, Christopher Biggins, Paul Burrell, Helen Flanagan and Fatima Whitbread.

Scarlett Moffatt, who won the 2016 series, recently said that she would be unlikely to sign up again because she didn't want to ruin the memory.

Asked about it, she said: "I was thinking about this because it has come to my attention. People have been talking about it but I just feel like my experience was so good in there and the people I was with, we’re still friends.

"Even though it was like six years ago, we’re still all active on the WhatsApp group chat and I just think I wouldn’t want to then tarnish that experience by going in again and maybe it not living up to expectations."
