Reality TV star Gemma Collins left fans thinking she was quitting I'm A Celebrity... Get Me Out Of Here! after she uttered the famous words in despair following a prank by former football manager Harry Redknapp.
Redknapp told the celebrities that they all had to take part in a late-night challenge titled "prison of hell" - just moments after they had returned to camp after completing another task during Friday night's episode.
The show, which is an all-star spin-off of the original and is set in South Africa, saw Collins sink to the ground, declaring: "I'm a celebrity, get me out of here.
"I'm done. I can't do any more."
The Only Way Is Essex star wiped tears from here eyes and held her head in her hands, as campmate Scarlett Moffatt looked on in shock.
Her outburst followed her breaking down on Wednesday night's show and confiding in former Emmerdale actor Adam Thomas: "I don't think I can take it."
However Redknapp then told the gathered campmates that he had been joking - and there was no late-night challenge after all.
"That was right up my street," a delighted looking Redknapp said.
"A proper wind-up. They fell for it hook, line and sinker. Oh, it worked a treat."
Collins explained that a prison task would have sent her over the edge.
"To me, it was claustrophic (sic). I would just have to say them fateful words," she said.
The episode also saw Collins open up about her views on body image, telling Moffatt: "We're under scrutiny all the time, and I never used to worry about it, but because everyone goes on about body image, this, that and the other, you then become like thinking you're disgusting and ugly every day.
"Because of all the pressure and, you know, people saying horrible things. And actually, I'm just alright as I am."
Collins later added: "This is me. I get sick of it - this diet, that diet, this pen, that pen.
"You know, at the end of the day, I think we've just got to accept all of us come in different shapes and sizes, and we can all be beautiful in our own way. It's really what's in your heart."
Friday night's show, which was filmed on Pussycat Doll Ashley James's birthday, also saw Olympic running champion Sir Mo Farah win 10 stars for the celebrities in a task that saw him have to crawl through and dig in containers full of snakes, insects, and even a crocodile.
The celebrities then had to take part in an evening task, which saw them have to balance a ball in front of them for as long as they could - with the other campmates eventually allowing James to win it as it was her birthday.
I'm A Celebrity... South Africa can be seen at 9pm on weekdays on ITV1, STV, ITVX and STV Player.
