The foursome were on a high yesterday after completing the iconic fan-favourite Celebrity Cyclone Bushtucker Trial.
The fun and games continued in to the early evening, when they performed their own camp musical.
It included self-written songs about some of the series' stand-out moments, including John's ankle sprain, Harry's love for jam roly-poly, and of course the many terrifying challenges they've endured.
Fleur closed the show with a rap that referred to Harry's wife. "Oh Sandra, look at this mob, get me out of here!" she said.
As the group sat down to a kangaroo dinner, they reflected further on their experiences in the Australian outback.
Emily revealed her highlight was the friends and family reunion that occurred the day before.
"Everything I have in my life I appreciate so much and will never take any of that for granted again," she vowed.
The Inbetweeners actress also credited the 'Viper Pit' Trial as being her turning point.
"It was one of the most frightening things in my life, but you need to know fear in order to overcome it," she commented.
"Igot 9 stars out of 10 and it set me on a really good path."
Fleur was glad she'd made friends for life, saying she'd remember their camaraderie in the Jungle Arms "forever".
Her worst moment was the 'Rotten Retrieval' Trial. "I was really scared, the most terrified I’ve ever been," she recalled.
"I feel like I can face anything now, I don’t think I will question myself anymore."
Harry enjoyed the roast dinner banquet, but wasn't so keen on the Doll House challenge, remarking: "I wasn’t crazy about that."
He also suggested he may regret performing karaoke at the Jungle Arms.
"Other than that for me to go and ruin Frank Sinatra in front of millions of people… it has been amazing and I’ve loved every minute of it," he laughed.
Meanwhile, John remembered having to conquer his fears of heights in The Edge.
"I thought, 'if this is the beginning, where are they going to go'," the Torchwood star explained.
"My best moment, even though I lost, was Drown and Out. One of my fears was being confined space in water.
"I got over it and got to know one of my friends I’ll have for life, and that was Emily."
