'If I was one of your children I'd kill myself,' he said with a vengeance.
Katie H actually looked upset and I really don't blame her. What a dreadful thing to say – this war of words is going too far now. Katie H asked Nadia if she though what Perez said was OK, and he continued "I would, I would blow my f**king brains out”.
Seriously Perez? If you were Katie's child you would shoot yourself in the head? This man is a disgrace.
Katie then hit back as she said her children 'loved their mummy' and 'had the benefit of a mother and father’.
This again was a low blow and Perez shouted 'Shut the f_ck up, b_tch! How dare you bring my child into this?’
Despite the fact it was him who first brought children into it, and in a very bad way. So what's good for the goose and all that Perez…
He also laid into Cami Li and repeatedly called her a b*tch too. How is this ok?
Perez spoke to Michelle Visage about his place within the house, telling her he felt like it was a witch hunt against him. Has he ever thought that if he stopped stripping off and dancing around like a performing monkey, the likes of Katie H and Cami Li would have to cut him some slack?
It makes me so cross watching him talking to the cameras and welcoming us to 'The Perez Show’. It's so selfish and he has ruined this experience for most, if not all, of the housemates and it's such a shame.
Michelle spoke frankly to him and he took it all in and gave her a hug, but I can't help but think that even that was a game plan: he has heard how much the public love her as they cheer her name on live eviction nights.
Trying to get Michelle back on side is a strategic move on his part: he's attempting to make a strong alliance with a popular housemate.
Michelle isn't stupid though, so I can't see her being sucked into his little game.
Big Brother must love all this tension and the arguments, because all the tasks given aim to encourage just that.
Even last night's shopping task saw Big Brother playing audio of what the housemates had said about each other into the house.
In order to win a luxury food budget, the housemates had to admit if it was them that said it. How mean is Big Brother?
Watching Cami Li, Nadia and Perez trying to guess who the public thought was most entertaining, the most untrustworthy etc, for another part of the shopping task was interesting.
It shows that when you're in there you really have no clue about what's being shown on the outside. I love how much the 'game plan tweet' annoyed Perez – it was good to see something get under his skin, just like he does to everyone else!
Talking of Cami Li, I really like her, I think she is funny and very straight talking, but whenever I tweet about liking her I only ever get a bad response. The public don't seem to like her and I really can't see why?
I've seen that Nadia, Katie H, Cami Li and Patsy will face the third public vote on Tuesday, and I think it will probably be Cami Li who goes. But, in this house, anything could happen…"
