The 70-year-old reality star - who is poised to face the first Bushtucker Trial alongside Kate Garraway - claimed that some of her campmates aren't quite aware of what they're getting themselves into on the ITV show.

Caitlyn said: "I don't think some of the people realise what they're getting into, it's not a vacation."

Caitlyn and pop star Nadine Coyle were asked to skydive from 10,000 ft on the opening show of this year's 'I'm a Celebrity' series.

And Caitlyn said she was "glad to share" the experience with the singer.

She explained: "Nadine has never done anything like this so I will do all that I can to help her out but I think after it's all over it'll be one of the best experiences of her life and I'm glad to share it with her."

Caitlyn - who has daughters Kylie, 22, and Kendall, 24, with ex-wife Kris Jenner - also revealed she was following in the footsteps of some of her famous family members.

She said: "Kendall has skydived, Kim [Kardashian West] has and I think Kourtney [Kardashian] has. I'm gonna do this, everyone in my family has done it."

Both Caitlyn and Nadine successfully completed the challenge, with the reality star subsequently admitting to being "very proud" of Nadine.

The campmates were subsequently divided into two groups, with Nadine, Adele Roberts, Roman Kemp and Myles Stephenson being based in the main camp.

Despite this, Nadine was less-than-impressed with her surroundings in the jungle.

Speaking about the state of the dunny, she confessed: "It's horrific. It's really really bad."

Meanwhile, in Snake Rock, Kate Garraway - who was joined by the likes of comedian Andrew Maxwell, Jacqueline Jossa, James Haskell and Ian Wright - admitted to being unhappy with her sleeping arrangements.

The TV presenter said: "We are sleeping on the floor, literally a piece of fabric. They don't look comfy."

However, she insisted that spirits in the group remained high - at least for the time being.

Kate shared: "At the moment, there's a really good team spirit and everyone is very much together. We're a proper team. The Rough Camp team."
