The 'I'm A Celebrity... Get Me Out Of Here!' cast of 2020 are going to Victoria Derbyshire's house on Sunday night to watch the start of the new series.
Vernon Kay - who finished third on the programme last year - says the cast of the 20th series are getting together at the TV presenter's abode to watch the launch of series 21, and they are getting their camp clothing back on for the occasion.
He said: "It's more of a celebration that we've done it and it's in the can. We're all going around to Victoria Derbyshire's house on Sunday to watch it.
"So that's going to be really good.
"I'm going to have my bandana on. [Vernon's wife] Tess [Daly] absolutely hates it."
The 47-year-old star also hinted this year's series could feature trials in the sea, as there were some planned for last year before they were axed due to the coronavirus pandemic.
He said: "I think it's going to be a lot more difficult for them this year than it was for us last year.
"Because we had really strict COVID protocols. We weren't allowed to go in certain areas, we weren't allowed to mix with the production team.
"We couldn't leave the castle grounds. This year I'm hearing they are going to leave the castle grounds.
"We did have stuff planned to do in the Irish Sea, but that all got canned because we couldn't leave the castle grounds.
"So I'm hoping it's going to get tougher, and colder. Because it's on a little bit later this year."
Vernon believes 'I'm A Celebrity' contestant Richard Madeley could "frustrate a few people" in the castle this year.
Speaking on 'Good Morning Britain', he added: "I can't wait to see Richard, I'll be honest with you, I think he's going to talk everyone to death. I think he may frustrate a few people but he's extremely intelligent and he's a great listener.
"And that's what you need in there because you get really tired and you open up and get really emotional because you miss your friends and family.
"Mo Farah got so bored with us asking about the Olympics but that's what made him blossom and shine and he just loves talking about those gold medals."
As well as Richard, former footballer David Ginola, Olympic diver Matty Lee, and former 'BBC Breakfast' host Louise Minchin are all taking part in this year's 'I'm A Celebrity', among others.
