The last live show of the series takes place tomorrow (Saturday) as four celebs battle it out for the Glitterball.
Competing alongside Debbie is Gemma Atkinson, Alexandra Burke and Joe McFadden.
But ahead of Saturday's show, Debbie has confessed she's been hit by illness.
"On Tuesday I was like a zombie," she told the Daily Star newspaper. “I was brain dead and physically washed out.”
As things stand, Debbie is one of two favourites to win Strictly on Saturday night.
With just three days to go until the Strictly Come Dancing champion is crowned, it appears to be a head to head battle for the title.
Despite a slight drift from 8/13 before the final, Holby City star Joe McFadden remains the firm favourite at 8/11.
Debbie McGee has made a last minute bid for the Glitterball trophy as she is cut into 2/1 from 5/2, having drifted out from 15/8 earlier in the week.
The jig looks well and truly up for one time favourite to win Alexandra Burke, as she is eased out to 13/2 from 5/1. Another outsider for the title is Gemma Atkinson, who is now 16/1 from 14/1 to win.
Aoife Heffron, Spokesperson for BoyleSports commented: “Joe McFadden is the one to beat ahead of the Strictly Come Dancing final this Sunday, however he has suffered a bit of a drift, to 8/11 from 8/13 as punters search for a big bet in the market.
"Despite this he remains miles above the rest of the competition and looks to be the likely winner.”
She added “Debbie McGee has been backed into 2/1 from 5/2 as punters appear to believe that the 59-year-old will clinch the Glitterball from Joe at the very last second.”
