The I'm A Celebrity Cyclone saw the four remaining celebs jetted with water cannons and giant balls - and it was a bit too much for Harry Redknapp!
The 71-year-old was up first on the giant obstacle course and had to grab the first star thrown to him by John Barrowman, 51.
But within seconds of jumping in the water, Harry decided he needed the loo!
He turned to John, who was on the sideline due to his ankle injury, and yelled: "I wanna wee, John! I wanna have a wee!"
Seconds later, he fell over and was washed back to his campmates Fleur East and Emily Atack at the start line.
The football manager's confession had viewers of the show in hysterics.
One tweeted: ""I wanna wee" [expletive] love you harry redknapp #ImACeleb".
I wanna wee, John! I wanna have a wee!
Another commented: ""I wanna wee" Harry is the best! #imaceleb".
And a third wrote: "Should of gone before you got there Harry "I want a wee" #ImACeleb".
Hosts Dec Donnelly and Holly Willoughby also cracked up at Harry's comment.
Dec, 43, shouted through his megaphone: "You can't wee, Harry! You can't wee!"
Holly, 37, added: "No, Harry!"
But at least the star appeared to enjoy himself, as he slid along the slippery obstacle course with a big grin...
Harry's co-star Fleur managed to help him back into his position, Emily, 28, was next and Fleur, 31, had the hardest job of going third on the tricky course.
It was certainly a close call!
The campmates just managed to complete the ten-minute challenge, with Fleur dashing to her post with seconds to spare.
Harry later joked: "I was supposed to be sitting at home in my house slippers coming up to 72 years old, not going up a water slide getting smashed in the face by balls."
Well, we bet your grandkids are proud, Hazza!
