It's the grand final of this celebrity gymnastics competition tonight, basically for all the famous folk who weren't asked to do Strictly. Actually, we're not even sure if all of this lot are famous really. The six finalists and their professional partners need to prove their acrobatic worth tonight with their floor and aerial trapeze challenges. Finalists include Lucy Mecklenburgh, Sarah Harding and Carl Froch... yep, the Girls Aloud name is the only one we recognise too there.
