The routines for the semi-finals have been revealed, and the CBBC presenter will be pairing up with his pro partner Amy Dowden to take on the powerful style.

Karim - who received the first 40 of the series from the judges after an eye-catching Jive set to 'You Can't Stop The Beat' from 'Hairspray' - will be delivering an Argentine Tango to 'Libertango' by Bond.

He and Amy will also treat viewers to the American Smooth set to Neil Diamond's 'Sweet Caroline'.

Kelvin Fletcher and Oti Mabuse will be looking to continue their impressive performances on the BBC's Latin and ballroom show with a Paso Doble soundtracked by 'Seven Nation Army' by The White Stripes, and a Quickstep to the 'Glee' version of 'The Lady is a Tramp'.

After delighting the judges and getting scored 39 for their Charleston over the weekend, Emma Barton and Anton du Beke will tackle the Cha Cha Cha to the sounds of 'Hold My Hand' by Jess Glynne, as well as performing a Waltz to Erik Satie's 'Gymnopedie No. 1'.

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."
