Top 14 according to the bookies:
Janice Dickinson
Hulk Hogan
Keeley Hazell
Chloe Jasmine
Dean Gaffney
Farrah Abraham
Gary Beadle
Gemma Collins- NO PLEASE
Tom Daley
Tulisa
Dina Lohan
Brian Harvey
Craig David
Dan Osbourne
The way to find out who's likely is by previous association or if they need cash, so...
Chloe and sadly Gemma maybe certainties as they are BB fans. Gary could do after Charlotte won and Ricci did last year, Dan could do because Lauren did it last year. Brian Harvey is likely and has been mentioned too much in the past for it to be a certain no. Keeley is the token English model and Farrah is the typical American contestant.
Janice could do it as she has done reality before.
I hear Craig David and Hulk need a bit of cash, so that could be likely.
The only one that points to a certain no is Tom.
If the likelies were the ones, I could already foresee a Gary V Janice Top 2. Janice has a good entertainment factor and if Charlotte won CBB, it'd be shocking if Gary wouldn't. However, he may not translate to the more sensitive BB fans compared to the Geordie viewers. He'd probably receive a lot of hate here at least.
Other betting mentions.... Sarah Harding, James Hill (that would have been more a last series thing as people would have forgotten him by now), David Gest, Ronan Keating, Kelly Brooke and Zayn Malik (yeah sure!), if a 1D person would go I would be Louis who is a huge fan.
