I'm A Celebrity All Stars is set to hit Irish TV screens next year, with Carol Vorderman, Amir Khan and Gillian McKeith leading the line-up.
Ant McPartlin and Declan Donnelly, who recently confirmed they were filming the Virgin Media show spin-off in South Africa, will of course be hosting the programme, which will feature 15 legends from throughout the show's history.
Amongst the record number of campmates, previous winners TV personality Georgia 'Toff' Toffolo, ex-cricketer and A Question Of Sport captain Phil Tufnell and former EastEnders star Joe Swash are said to be taking part, Mirror UK reports.

Other big names reported include Coronation Street babe Helen Flanagan and singer/presenter Myleene Klass - both of whom sent temperatures soaring during their steamy shower scenes in the Australian jungle in their respective series.
Gillian who famously almost passed out whilst taking part in a Bushtucker Trial back in 2010 is also rumoured to be returning - as does her popular campmate, Happy Mondays frontman Shaun Ryder.
Soap stars Dean Gaffney, who shot to fame in his role as Robbie Fowler in EastEnders, and Coronation Street's loveable Andrew Whyment (Kirk Sutherland) will both be hoping to be crowned King in 2023.
Princess Diana's former butler Paul Burrell has also signed up, and he will no doubt wow campmates with tales of the late Queen Elizabeth II.
There will be a 2016 reunion in the form of Countdown star Carol and her co-star Jordan Banjo - of Britain's Got Talent winning group Diversity.
Completing the All Stars line-up are British boxing hero Amir Khan, 2007 runner-up Janice Dickinson and Olympian Fatima Whitbread.
An show insider told the Sun : "It's a different format to Australia, who knows when and where celebrities will enter camp, literally anything could happen. It's not clear how many will start in camp or how many will be there by the end when one is crowned King or Queen of the jungle, possibly for a second time.
"It's the best of I'm A Celebrity, quite literally, but there's some twists and surprises along the way for viewers and campers so it's not going to be as straightforward as they might think."
The All Stars series of I'm A Celeb, which will take place in South Africa's Kruger National Park rather than Australia, is set to run in addition to the usual annual Virgin Media programme in 2023.
Ant and Dec took to Twitter on Thursday to confirm the new show would be going ahead as they shared a video on the platform.
"South Africaaaa! That's right, we're filming a very special version of I'm A Celebrity in South Africa, which is coming to your tellies in 2023," they revealed alongside the clip.
"We've got news," Dec added: "It's probably the worst kept secret in television, but we can confirm we're 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."
Series hosts Ant McPartlin and Declan Donnelly were spotted in the airport arriving home from filming I'm A Celebrity All Stars on Tuesday, however, no other rumoured cast members have landed yet.
The All Stars series of I'm A Celeb is set to run in addition to the usual annual Virgin Media programme.
It has already started filming in South Africa but the show won't air until 2023.
