The Celebrity SAS: Who Dares Wins campmates got very comfortable with one another, thanks to Fatima Whitbread stripping completely naked.
The Olympic javelin star, who at 61 is the oldest contestant ever, stripped naked straight away in the communal showers, and encouraged the others to be comfortable in their own skin.
Fellow Olympian, sprinter Dwain Chambers, 44, said: "Day one or two, Fatima would just walk past us naked. I was like, what?"
Other celebrities, including TOWIE star Ferne McCann, said Fatima was "inspiring" with her carefree attitude, and helped the others in the cast to feel more body confident.
Which is handy, as they also had to go to the toilet while "looking into each other’s eyes."
Ferne, 32, said: "I really respected her. You’re totally exposed and you have to get over it.
"I think that the older you are, the more comfortable you are in your own skin and body, and she just stripped off. She encouraged me to just wash.
"You’ve got to find these comforts in that environment. It sounds ridiculous. She brought so much light and joy for all of us."
EastEnders actress Maisie Smith, 21, said: "If I’m anything like Fatima when I’m 60, I’ll have won in life."
Fatima also entertained the cast with her flatulence. Maisie said: “She farts all the time.”
The new series, filmed in the desert in Jordan, continues on Sunday at 9pm on Channel 4.
