Adam Peaty is swapping the swim shorts for dancing pants in the new season of 'Strictly Come Dancing'.
But can he move on the dance floor as smoothly as he glides through the water?
We'll find out next month when the 19th series of the dance contest will be aired on Britain's national broadcaster BBC.
Peaty is one of the 15 British celebrities joining the show, following in the footsteps of boxing Olympic champion Nicola Adams, who last year was the first contestant to perform in a same-sex partnership.
"I'm not the most fluid on land," the 26-year-old admitted to BBC Radio 1 Newsbeat.
"But, saying that, I am an athlete. I am used to working hard. Hard work is in my blood."
Peaty ended his Tokyo 2020 Olympics with three medals, two of them gold.
By winning the 100m breastroke event, he became the first British swimmer to retain an Olympic title.
Now it's time to take some rest and look at this new challenge.
"It's going to give me a new lease - just the way I look at swimming and look at training," he said.
"If I take too much time out of physical training, I get fat, I get big, I put too much muscle on."
'Strictly Come Dancing' will also give him the opportunity to test his comfort zone:
"Whereas Strictly is going to keep me fit, it's going to be a change of stimulus, I'm going to do stuff I've never done before and hopefully have a lot of fun.
"I've swam for seven years and I've gone through the constant cycle of championship, go back to training, go back to the drawing board, another championship and another championship, but I've never truly been uncomfortable."
Peaty will swap swimming for salsa, the diving board for ballroom dancing, and it's going to be a lot of fun.
A fierce competitor in and out of the water, don't be surprised to see him waltz his way to the winning prize.
