Businessman Duncan Bannatyne called Lady Colin Campbell a "nasty woman" during a row over soup on I'm A Celebrity ... Get Me Out Of Here!
The author, dubbed Lady C on the ITV show, had purchased a can of soup using "dingo dimes" from the vending machine.
However, she clashed with the Dragons' Den star over whether to share it with the hungry campmates in Snake Rock.
Meanwhile, Made In Chelsea star Spencer Matthews has left Australia after dropping out of the jungle game show.
The TV personality boarded an Etihad Airways flight at Brisbane Airport to begin his journey back to London.
Matthews made no comment, but he smiled for the assembled press and well-wishers, and even gave the thumbs up gesture.
Back in the jungle, the Croc Creek team returned to camp following their successful live Bushtucker Trial win on Friday. Their reward was a luxurious feast, which did not include the members of Snake Rock.
"Shall we all agree that we offer them a quarter of the tomato soup?" asked Lady C.
"No, they can have the whole bloody tin," Bannatyne said. "They've been starving for three days and we've got the banquet."
Spandau Ballet's Tony Hadley tried to make peace, but Lady C turned on him.
She then called Bannatyne a "mouse" and a "little p***y".
He accused her of a "lack of breeding" and added: "What a nasty woman you are."
But the argument continued even after the Scottish businessman branded her "the most selfish person" he had ever met.
The Croc Creek camp mates were treated to a luxurious suckling pig banquet for winning live trial Cocktails & Screams.
As losers, Snake Rock's penalty was the Trailer of Torment.
The celebrities faced numerous critters including snakes, cockroaches and spiders. They were also played a video of Croc Creek's banquet.
However, they endured the trial.
Later, Union J star George Shelley cried in front of Susannah Constantine. The fashion star comforted him and they hugged.
On Friday, ITV said late entrant Matthews had departed "on medical grounds".
He had to leave I'm A Celebrity because he was taking "steroid-based medication" to bulk up for a charity boxing match.
In a statement, the 26-year-old said admitted he had made a "serious error".
He said: "Shortly after I arrived in Australia I told the production team that I was taking a steroid-based medication that had begun some weeks ago.
"When I started taking this programme of pills it was in preparation for a charity boxing match which, ironically, never took place."
He added: "Taking these pills was a serious error of judgment, which I hugely regret.
"I have disappointed my family, friends and fans and would like to apologise. I would like to thank ITV for the opportunity and their support, they're a class act.
"I loved every minute of being in the jungle and wish the remaining contestants the best of luck. Hoping for another shot at it some day."
I'm A Celebrity ... Get Me Out Of Here! is broadcast on ITV at 9pm.
