Another year, another Olympic gold medallist - and he has big shoes to fill after the legendary Sir Mo Farah appeared in the castle last year.
Matty Lee, Tom Daley's diving partner, will be hoping to win over I'm A Celebrity viewers and be crowned the first King of the Castle, which will be the "cherry on the cake" of a perfect year.
During the summer, Matty dove to victory with Tom as they won their first gold in synchronised diving at the Tokyo Olympics.
And he was approached for I'm A Celeb just minutes after achieving the fantastic feat.
“Nothing ever prepares you for what life will be like after you do well in the Olympics," he said. "I was and still am mainly in shock that I am doing I’m A Celebrity.
"My two childhood dreams were to win an Olympic medal and take part in my favourite TV series. And now I am doing both this year!
“My family is buzzing about it all. We were on the way back from the airport where they had picked me up from Tokyo when I got a call about the programme.
“When I told Tom, he was in shock too! He is so excited for me and he has always been so supportive and helped me a lot over the past three years. He gives me advice about anything whether it is relationships or whatever - I always ask Tom.”
What does he want the public to discover about him?
“Everyone knows who Tom Daley is but people don’t necessarily know who I am.
“But without each other, we would never have achieved what we have achieved. He always gives me credit where it is due and I also do too. He is really happy for me to grow as an individual and I think it is a chance for people to get to know me better.
“I watched our Olympic final again the other day andI realised I look a bit angry but that’s just me being in the zone! I am not like that at all in real life!”
Phobias?
“I am really looking forward to the Trials and also, to be around different people will be fun too. I amused to just being around athletes. I think I will definitely freak out at rats and I know I will scream.
"Heights won’t be an issue though! I am obviously used to diving off 10 metre boards!”
Odds of winning?
16/1
