Many of the stars on the ITV contest have become favourites with fans this series.
But Fleur could claim the title of Queen of the Jungle at the last minute.
The singer has seen her odds of winning I’m A Celebrity…Get Me Out Of Here! slashed in an exciting turn of events.
Ladbrokes have seen her odds fall from 33/1 to 9/2 in under a week.
However, it’s Harry Redknapp who is still the front-runner as he has odds of 8/11 according to the bookmakers.
Emily Atack is currently just behind Harry in second place with odds of 4/1, meaning Fleur is in third place.
A spokesperson said: ”It’s fast becoming a three-horse race for the I’m a Celeb crown and while ‘Arry heads the betting, Fleur’s odds are tumbling thick and fast.”
But as Fleur is the one who has had the biggest shift in odds, so she could well win the contest.
It comes after Simon Cowell took a dig at the former X factor contestant.
During Saturday’s live show he told his act Scarlett Lee that he didn’t want her “in the jungle” in a few years time.
He said: “I don’t want you in the jungle in two years time drinking worm juice.”
Simon then continued: “I want you on Broadway or on the West End selling records. You’ve got a big duet to come, Scarlett. This could change your life.”
But last night Declan Donnelly in turn make a cheeky comment about the music mogul.
As Fleur competed in a gruelling challenge where part of it saw her hit at piñatas to release stars, Dec told Fleur to “picture Simon Cowell’s face” as she smashed it.
But Fleur does have one very interesting supporter, who is a relative of one of her competitors.
Nick Knowles’ brother John has said he’s placed a bet on the 31-year-old.
The admission came as he appeared on Loose Women today.
He said: “My money is on Fleur – if I said today my money is on Nick he would say afterwards: ‘You shouldn’t have said that, you didn’t mean that’.
“Fleur has done fantastically well and she is very popular.”
I’m A Celebrity…Get Me Out Of Here! continues tonight at 9pm on ITV.
