Realistically I think it will be something like this:
Peter Andre
Paul Danan (have been waiting for him to be on it for years, an he has done a couple of Channel 5 shows before
)
Ex Hollyoaks actor
Old guy that no one knows
Token black American rapper/RnB singer that hasn't had a hit for at least 5 years.
Amy Childs
Older woman from a different country that not many people know of
Random girl that has slept with a footballer and it became public knowledge
Singer that hasn't had a hit song for at least 5 years
Star of a TV show that is currently on air but isn't as popular that it used to be, and is probably on Channel 5
