Richard Madeley - TV presenter & journalist
Good Morning Britain host Madeley was rumoured to be taking part this year and then fuelled speculation further by mysteriously going missing from screens around the time the cast's isolation period began, shortly after signing a deal to host the ITV breakfast news show.

Madeley admitted he was looking forward to the trials, having been a fan of the show for years.
He said: "I really hope I do get voted for the trials. The thing about this programme is you mustn’t go into it if you take yourself remotely seriously. I don’t and I am thoroughly looking forward to being covered in god knows what."
The broadcaster's son-in-law James Haskell took part in the 2019 series, and Madeley himself is no stranger to TV contests as he competed in The Circle in the same year.
Louise Minchin - Broadcaster & ex BBC Breakfast host
Madeley will be joined in camp by a fellow broadcaster - Louise Minchin, who recently quit her long-running role hosting BBC Breakfast and had been rumoured for camp.

BBC Radio 1Xtra DJ Snoochie Shy reveals she is a big ‘scaredy cat’. The 29-year-old DJ, who landed her 1Xtra late night slot two years ago, also reckons she could be so frightened doing the Trials that she may not even be able to let out a scream.
Danny Miller - Emmerdale star
Emmerdale star Danny Miller admits he agonised over whether to take part in this year’s I’m A Celebrity because it meant leaving his new baby behind.
This year's sports stars in camp include football legend David Ginola, Olympic Gold medallist Matty Lee and Paralympic Gold medallist Kadeena Cox, who recently won Celebrity MasterChef - which is sure to make her a popular campmate with the other contestants.
David Ginola - Football Legend
Football legend David Ginola admits he always ‘sets out to win’ anything he does as he eyes up the ‘King of the Castle’ crown and reunites with some very special fans of his old club, Newcastle United – Ant and Dec.
Matty Lee - Olympic Gold Medallist
After winning Gold with Tom Daley in the 10 metres synchronised diving at the Tokyo Olympics this summer, Matty Lee admits it is the ‘cherry on the cake’ to be taking part in his favourite TV show.
Kadeena Cox MBE - Paralympic Gold Medallist
She is a four time Paralympic gold champion and one of the British stars of this year’s Tokyo games but Kadeena Cox readily admits going on I’m A Celebrity will be mentally tougher than anything she has ever done before.
Fans of the show may have noticed that the cast of 10 is a little smaller than the full cast of 12 in previous years, but with late entrant celebrities often introduced after the series start, we're expecting to see a couple more contestants head into the castle.
I'm A Celebrity...Get Me Out Of Here! begins on Sunday, 21 November at 9pm on ITV.
