Alex Jones hosts as 10 celebs perform show-stopping routines with professional partners. Carl Froch, Sarah Harding, Peter Duncan, Lucy Mecklenburgh, Amelle Berrabah, John Partridge, Ian 'H' Watkins, Emma Samms, Bobby Lockwood and Andrea McLean have been through the grueling training process and are about to show us what they've got.
All 10 of them will perform this week – five doing acrobatic floor routines and the remaining five showing us their skills on the aerial hoop.
Judges are Olympic gymnast Nadia Comaneci, Olympic gymnast and Strictly star Louis Smith, Commonwealth gymnast-turned-commentator Craig Heap, and aerial performer and choreographer Sebastien Stella. They'll be scoring the contestants out of 10.
Louis Smith will also treat us to a performance as he leads five Team GB male gymnasts in a routine.
