Mark Wright and his fellow I'm A Celebrity contestants were horrified to find a huge python had slithered into the middle of the camp and was killing a rodent.
Mark discovered the intruder under his bed as he and his blue team campmates tried to settle down to sleep in the Australian jungle.
He and the other contestants - who included McFly's Dougie Poynter and DJ Pat Sharp - were said to have been left "terrified" by the ordeal.
The Only Way Is Essex star Mark at first thought he had spotted a rat. But on closer inspection he noticed the creature was being suffocated by the snake.
"Oh my God Dougie, there's a snake eating a rat," he shrieked.
Security staff had to step in to ensure the safety of the stars in the jungle camp after the 1.5 metre carpet python was spotted.
