Fred Sirieix was left "black and blue" after a diving failure.
The 52-year-old TV star, who hosts the Channel 4 dating show 'First Dates', revealed he had tried diving with his Olympic diver daughter Andrea, 17, but emerged from the pool covered in bruises.
Speaking to the Metro Sixty Seconds column, he said: "I tried diving for five days with my daughter Andrea – who's an Olympic with Team GB.
"I was left black and blue, I got bruised everywhere, it was so painful.
"I was scared every time I was on the board. My daughter was on the ground and she said, 'Daddy, you've got to relax, we can see your heart beating in your chest.' I can't believe she saw that."
Despite his diving failure, the maitre d' is still an accomplished sportsman, and left 'I'm A Celebrity … Get Me Out Of Here!' viewers shocked after he revealed his impressively toned body.
Speaking of his routine, he said: "I exercise six times a week and I do 20 minutes of basic bodyweight exercises or 301 push-ups, 100 squats and 100 reverse squats, which takes me 20 minutes.
"Then I was on the bike for 20 minutes and I did 15 minutes of various exercises with free weights.
"It's basically about getting your heart rate up for 20 minutes a day. The older you get, the more you realise it's about mobility."
Fred, who was the third star to be eliminated from the ITV show, admitted that he struggled the most with food in the camp.
He explained: "In the morning, you're given the rice and bean portions and you have to decide what you cook and when you're cooking.
"So, we’d usually have rice in the morning, beans for lunch and then keep something back for the evening.
"By the afternoon, your energy levels go down but you need to save energy to get water and wood. That's when you get hungry."
