Here's a picture run down of the celebrities who are set to vault for votes on BBC's Tumble.
A total of ten stars have been in training for the new series, learning a series of tough and strict gymnastic disciplines with a pro partner.
They include Carl Froch, Sarah Harding Lucy Mecklenburgh, Amelle Berrabah, John Partridge and Ian ‘H’ Watkins.
Also in the line are Emma Samms, Bobby Lockwood and Andrea McLean.
But Mr Motivator was forced to pull out after dislocating his knee in training, meaning he won't even make the first live show.
All of the celeb contestants have been put through a gruelling training process and are now ready to show the great British public what they can do.
At least, they better be!
In Saturday night's first episode, all 10 celebrities will perform show-stopping routines with their pro partners.
Half will do acrobatic floor routines while the other half have been challenged with a performance on the ‘aerial hoop’.
The judges - Olympic gymnast Nadia Comăneci, London 2012 gymnastics medallist Louis Smith , Commonwealth Games gymnastics champion Craig Heap and aerial performer and choreographer Sebastien Stella - will score the celebrities on the quality of their performances and out of a maximum of 10.
Tumble starts at 6:30PM this Saturday night on BBC One.
