Scotsman Jason's odds have deteriorated, leaving him still the favourite to be evicted this week, as he goes from 4/11 to 1/9.
The wannabe page-three model's odds have fluctuated wildly during her time in the house. During the boot camp task, her fiery arguments with former refugee Ahmed saw her chance of winning the competition rise as high as 2/1. However, her antics with Stuart, including her very vocal dissatisfaction at not being allowed to "marry" him during the wedding task, could have turned viewers against her.
Ladbrokes spokesman Warren Lush said: "Punters have a strong feeling that Michelle could walk on Friday although Jason remains odds on favourite to go."
Posh Shell is 25/1 odds to go on Friday, Stuart is next on 33/1, while Dan and Nadia, hot favourites to win the competition, are tying on 40/1.
All of the housemates are facing eviction this week because 'Big Brother' scrapped the nomination process.
Favourite to win the show is Nadia on 2/5, then Dan on 3/1, followed by Stuart on 8/1, Shell on 12/1, Michelle 16/1 and Jason, the rank outsider, on 50/1.
The housemates' latest task will see them chained to each other for the three days. The pairing is bound to cause arguments as Shell is chained to Michelle's loverboy Stuart, while Michelle has to put up with surly Jason, and Dan is chained by the ankle to Nadia.
The chaining-together was decided on weight, with Shell and Stu being the lightest, Jason and Michelle being middleweight, while Dan, who topped the scales at 14 stone and Nadia at 11 stone 13lbs, came under the heavyweight bracket.
On hearing the news, the housemates laughed. Michelle told Shell and Stuart: "I am going to lay down some ground rules."
Shell reassured the Geordie. "There's nothing to worry about, we're just joined at the hip."
If the housemates complete the task they will be treated to a message from their friends and family, and next week's shopping budget will be doubled. If they fail, they will not receive the treat nor any shopping.
