While the viewers watching at home were left gobsmacked by Debbie, so too were the judges, who scored her an impressive high first score of 30.
Usually the harshest critic on the panel, Craig Revel-Horwood said Debbie “looked like a 20-year-old” on the stage, while Darcey Bussell said she was “on fire” and new head judge Shirley Ballas commented that she “has it all”.
Her comments may not have been as pleasing had her performance turned out anything like her rehearsal, which she says was a disaster.
The former magician’s assistant – whose husband, magician Paul Daniels died from a brain tumour last March – is now even favourite to win the show following Saturday night’s episode.
Bookmakers William Hill have now slashed their odds on Debbie to win from 20/1 to 6/1.
