Royal family member Mike Tindall is heading into the jungle for I’m A Celebrity... Get Me Out Of Here, saying the biggest challenge will be missing his kids and the risk of turning "hangry" on a rice and beans diet.
The former England rugby player, who is married to the late Queen’s granddaughter Zara Tindall, will now head into the Australian jungle for the ITV show.
Speaking for the first time about signing up, Tindall, 44 - who helped England win the 2003 Rugby World Cup - said: "It should be good fun, why not? It is always worth a go isn't it."
Told it was the first big reality series a royal had done since It's A Knockout, he added: "No one said that when I did Bear Grylls and The Jump and I just do things I think will be fun."
And told he could be King Mike of the jungle before Charles had his coronation he laughed and said: "I am not really thinking about that to be honest."
Tindall married the Princess Royal’s daughter in 2011 and the couple have three children, Mia, Lena and Lucas Tindall.
He said: "Australia is a special place yeah, I met Zara in Sydney. There is no holiday planned at the moment afterwards. If there was I wouldn't tell you either!"
Turning to discuss the show and what he will miss whilst in camp, he said: "Hanger is always going to be the biggest thing to worry about, but I have also got three kids so going without sleep goes with the territory. Again you are stepping into something you don't know.
"The family I will miss the most of course. This will probably be the longest time I have been away and then not having communication, that will be the hardest bit. But also you get your head around what you are doing and try to win some stars. I want to win stars because I want to eat."
Before signing up he also took advice from former contestants and admitted he had been "on the fence' for a while before agreeing to take part.
Speaking as he waited for his bags at Brisbane airport, he said: "We will find out if Im good with snakes wont we? I hope I will be good at the trials but you don't know what you are going to get.
"I have spoken to James Haskell about it. He was one of the guys who said you should do it so I took some advice from him. Nick Knowles is a good mate of mine too so I have spoken to a few people.
"I was always on the fence but I do think it will be good fun at the end of the day. That is the thing, I like groups of people and I like things that could be good fun. So let's see, I might regret it."
Tindall joins a host of other stars isolating on the Gold Coast ahead of the series including radio DJ Chris Moyles, Love Island star Olivia Attwood and soap stars Sue Cleaver and Owen Warner.
The new series kicks off on November 6 on ITV.
