Split into two teams, the ten contenders for the King or Queen of the Jungle crown were taken to a barren island and instructed to race each other to the other side where a helicopter would take the winners off for one last night of luxury.
Losing team Snake Rock, led by former Pussycat Doll Ashley Roberts, were forced to get used to outdoor life one night early.
Setting up a basic camp, a heartbroken Ashley said: "I don't know what I'm doing. I'm totally out of my element."
Teammates MP Nadine Dorries, actor Colin Baker and darts champion Eric Bristow received more bad news when Made In Chelsea star Hugo Taylor announced he had lost the first Bushtucker Trial of the series.
Hugo failed to secure dinner for the group against a triumphant David Haye.
Hugo said: "I'm just hungry and tired and feeling a bit over emotional. I didn't expect to cry this early. It's hard to rationalise when your body is saying you need to eat, when you need to sleep. It's just terrible."
When I walked in you could see people's faces looking saying 'do you have good news?' I think immediately they could tell that I didn't.
Hugo described his first night in the jungle as "the weirdest camping holiday I've ever been on", while Colin said he "wasn't expecting to sleep on the floor which is probably full of 19ft tarantulas".
On her arrival at the Snake Rock camp, Nadine expressed confusion over the sleeping arrangements when she noticed a set of groundsheets.
The politician asked: "Where do the beds go? I thought we were up off the ground. I thought there were hammocks."
She went on to admit she felt "worn out" after delegating duties to her camp-mates, one of which was emptying the camp toilet.
"We have to empty the toilet out with our hands. We have to empty out the toilet ourselves," she said.
Hugo was quick to strike up a political debate with her.
"In Westminster, politicians really have to crack out of this fusty, old-fashioned impression everybody has," she told the reality TV star.
"They think everybody lives in landed estates; everybody's out of touch with real people.
"I think MPs have really got a responsibility given all the bad press we've had recently to get out of Westminster and communicate with people on a different level," she added.
That's one of the reasons why I'm here. Sixteen million people watching this show. That's how politics should be.
Hugo asked Nadine is she would ever like to be Prime Minister. "God no," she replied. "Never in a million years."
Meanwhile, former Coronation Street star Helen Flanagan is struggling to adjust to camp life and refused to eat the dinner cooked by Eastenders star Charlie Brooks.
She also complained to Loose Women panellist Linda Robson that she heard a rat and screamed that a bug had bitten her face. She then gave a warning to her campmates about how to conduct their toilet habits while in the camp.
"No-one is allowed to do a number two while they are here," she said.
The actress then confided to presenter Brian Conley: "How come everyone is so much better at doing stuff than me?"
She later confessed to Charlie and Linda: "I don't think I'm going to be very popular because I'm squeamish."
Linda replied: "You might be popular to do the trials."
Admitting that she thinks she will annoy campmates by not pulling her weight, Linda muttered: "You will cause I'll make you do it!"
Helen finally declared: "I'm going to go and give myself a spray tan and do something constructive."
She is set the face Nadine in the next Bushtucker Trial, which will be aired on Monday night.
