Louis Smith and Nadia Comaneci are to judge Tumble on BBC One.
The Olympic gymnasts are among the four panellists who will critique the gymnastic skills of 10 celebrities in the new Saturday night primetime show this summer.
Gymnastics legend Nadia will serve as the show's head judge and will be joined by former 'Strictly Come Dancing' winner Louis, former Team GB gymnastics captain Craig Heap and renowned aerial artist Sebastien Stella.
Nadia said: "The celebrities are going to be put through a fitness, gymnastic and acrobatic training regime that's like nothing they'll ever have experienced, and I can't wait to see the results!"
Louis added: "I know how scary it is to be on a live Saturday night entertainment show, so I'll definitely have a bit of empathy with the celebs on that!"
In addition to the judges, 'The One Show' presenter Alex Jones will host the six-part series and Olympic gymnast Beth Tweddle will serve as mentor to the 10 celebrities as they learn a number of gymnastic disciplines such as tumbling and double trapeze.
Alex said: "I am thrilled to be hosting this exciting new show which is sure to offer jaw-dropping stunts and a visual spectacle. No-one has told me yet whether I will be required to don a leotard or master the balance beams but I am willing to give it a go."
