I'm also surprised at Paul Danan and Callum Best. They were everywhere around 8 years ago.
Janice is another, it's odd that they haven't got her, surely they haven't been trying enough. I mean, she is worth more than a lot of what other people get. Why spend ridiculous amounts of money on dull people when you can probably get Janice for cheaper?
I'm surprised they haven't reached out for Chico and Shayne Ward or something... or someone that is from Hollyoaks. It would be a perfect time for Jennifer Metcalfe surely. Or Neil Patrick Harris, I mean, come on, that's an easy one. He went in the BBUSA house as a guest more than once, and didn't want anything in return as he is a big fan of BB. He even tweeted during CBB9 that he wanted to take part in the UK series and was watching it.
