Perez, whilst refuting the tweet about him using Nadia, said something about the interview with the Sun and they had taken it out of context. He obviously had no idea he was going to bond with Nadia before entering the house so can only assume that he spoke to the Sun inside the house.
If this is true, it really takes away the element of "let's put people in the house for x no of days who have no idea what's going in the outside world"

The interview took place before CBB, by his own admission Perez had spent a lot of time researching the people rumoured to enter and look up some of their work. He mentioned a few people in the interview

No, it was before he went in.

But odd how he knew exactly who he'd be in there with and others didn't - a point rarely picked up on when people support the man.

Everyone in there was rumoured beforehand, he clearly did his research on his potential future housemates. I don't find that "odd", nor do I see why that should make a difference to those who support him.

it was leaked way before the launch night - it was all over this forum days before it started who was going to be in.....

Of course he'd know who was going in, their is what he does for a living!
