Finally, Chris Ramsey and Karen Hauer - who defeated Alex Scott and Neil Jones in a dance off to earn their semi-final spot - will be dancing the Rumba set to Jorja Smith\'s hit \'Don\'t Watch Me Cry\', while their Viennese Waltz will play out to Queen\'s iconic track \'Somebody To Love\'.

Explaining her decision to save Chris and Karen, head judge Shirley Ballas has said: "[They] did some advanced steps.

"This is a man who started out with zero training and even though the footwork wasn\'t 100%, his timing was outstanding, and he really attempted to do his heel leads."
