Irish model Nadia Forde comforted fellow contestant Gemma Collins as she cried over her porridge and was convinced she had malaria.
The TOWIE star became anxious after she had a bout of diarrhoea while staying in the 'Slammer'.
She feared she had malaria.
She told fellow contestant Vicki Michelle: "I feel like I've got malaria. My poo is bright flourescent yellow. I've had the worst diarrhoea ever."
Vicki advised that her body might be "detoxing" as it has never experienced a diet such as the one in the jungle.
Later, Gemma said life in the jungle "slammer" was hard.
"Even a murderer gets fed three times a day," she said.
At this stage, Coronation Street actor Craig Charles, who plays cab driver Lloyd in the TV3 soap, told her off for saying she was "starving" when people in developing countries had to go without food.
This seemed to prompt a change in attitude for the TOWIE star.
"I've realised I must be strong.
"I pledge tonight, if I lose weight I'll be happier, that I'm never ever going to mention starving again."
At one stage Nadia was seen to comfort Gemma, reminding her they were only due to be in the 'slammer' for a few days.
Gemma, Craig and Nadia were left in the celebrity slammer after former footballer Jimmy Bullard put friends before food and opted to give up one of the stars he earned in the bushtucker trial and free Vicki Michelle to join the rest of the contestants in the camp.
Bullard, who had to dodge snakes and crabs in an underwater challenge, said he had "bottled" it but still managed to find four stars.
Collins, who had earlier told her camp mates she thought she had caught malaria, was upset she had not been freed and told her new friends: "I want to go. I'm not going to be able to do it."
The three remaining Slammer celebrities were then given giant knitting needles and told they would get a biscuit for every 10 rows knitted, but Collins soon lost interest saying: "What's the point, they are treating us like morons, I'm sorry but for a biscuit? Of course I want biscuits but I can't knit. I'm so hungry and dehydrated and on the verge of dying, I don't have the mental capability for it."
Meanwhile Jimmy Bullard struggled with his first bush tucker trial, Tunnel of Terror, in which the footballer was submerged in an underwater passage with snakes, crabs and other creatures.
Next to face a trial will be rapper Tinchy Stryder, who the public voted to take on the Chamber of Horrors to win food for his campmates.
As a journalist Michael Buerk has witnessed war and insurrection, flood and famine, and now to add to the list of extraordinary things the 68-year-old has been party to over a long career is the sight of Playboy model Kendra Wilkinson “twerking” for his delectation. “It’s not quite the greeting I get at the Garrick Club,” he said.
