Christen definitely contacted Channel 5. Looking at his Instagram, he's friends with Louise Ciffe who was to appear on CBB, and knowing contacts to the show helps, like Spencer Pratt and Stephanie Pratt.

Ellieen and Jack I have a feeling we're found though TV. Ellieen being on The X Factor and Jack had a video that went Viral.

Kieron and Danny I feel didn't audition but we're found on StarNow or something to have the careers they had I don't think they would have so many 'ex celebrities' audition.

Aaron - I think Channel Five wanted him for the stars he been with and been around. He seems good friends with Brooke Candy and Rita Ora, I'm not saying he didn't audition but I think him to name drop in his video would of got him fast tracked though Audtions.

Sarah, Harriet, Chloe - Sarah doesn't have much about her so I think she would of applied like normal people same with the others..

What do you guys think??

I know I've heard a number of them talking about auditions (Joel said his mum persuaded him to audition even though he'd never watched BB, for example) - and Jade was saying about how Derek Laud is her favourite housemate of all time, so I'd say she's a fan.

Maybe. I can see them going to Audtions

Jamie East tweeted the other day saying he remembers most of them from auditions back in C5's beginning

They all come from auditions. Those that are contacted by C5 are only invited to come to the auditions (or rather the call backs, as there are no real 'auditions' any more other than submitting an online form)

Was Jade part of the deal with TV3?

They've had plenty of Irish contestants before so doubt it.
