The odds have been up and down all week, but Ashleigh Coyle has remained firm as the odds on favourite, despite her price drifting over the past 24 hours.
Paddy Power reports strong backing for blond bombshell with one ballsy punter lumping on £750 just this morning.
Christopher Hall is now third favourite at 4/1 with Helen Wood now the 7/2 tip to be this year’s winner, having had her odds slashed from a previous 22/1.
Her abusive tirades and at times worrying lack of self-awareness have made this series one of the most explosive ever and despite campaigns to get her kicked out nothing has stuck and now Teflon Helen looks like she could do the impossible and pull a winner out of the bag.
Ash Harrison's have also been slashed and while still an unlikely 14/1, him winning could cost the bookmakers over £100,000 after a string of big bets.
Having been a favourite to win for a number of weeks in the middle of the series, it seems that Chris R Wright has fallen out of favour, with odds of 33/1.
That's the same as Pav Paul as it looks likely to be a case of last in first out this evening.
A spokesperson for Paddy Power said: “If Helen’s odds keep shortening at the rate they have been this week, she could soon be adding Big Brother to her list of conquests”
Big Brother airs at 9PM tonight on Channel 5.
