House mates that are ex-guinea pigs

[Foebane100]

I would be interested to find out the names of house mates that were guinea pigs in the house before being chosen as house mates, from this series or before? I’d be interested to find out how what percentage of them has been in the house before.

[Lil-Lindz]

Me neither I read this threadbut though "better keep my mouth shut" cause I have know idea what they are talking about lol

[Foebane100]

guinea pigs - People that have been in the house before testing it all works. Not on the show, but have been in the house while they tested it.

Oooh I get it

Imogen was a stand-in for Big Brother 4 aswell

[Foebane100]

I think Kinga or Orlaith had been in the house as test subjects before.
Isn't it a bit strange that people with prior contact with the Big Brother experience get in the house?
