The odds have in fact more than halved in the last 48 hours alone, according to Ladbrokes.
Momentum is fast gathering for White Dee since her episode with Gary flashing at her, and it appears the Benefits Street star is the new favourite amongst punters as her odds have been slashed from 20/1 into 8/1 since Monday evening.
It reminds us awfully of what happened to Helen's odds in the final week...
As it stands Gary remains the favourite to win but his odds have drifted out slightly to 8/13 following the sustained support for Dee.
Jessica Bridge of Ladbrokes said: "The monster of all gambles is currently taking place on Dee causing a huge upset to Gary's hold on the CBB crown.
"It's a sense of de je vu for the bookies as the same happened with Big Brother winner Helen back in August."
She added: "It's safe to say Dee won't be going back on benefits once she's out of the house."
