Yesterday, we saw Katie and Perez clash in the garden while she was trying to workout and, today, the mum-of-three has made it her job to wind the US blogger up.
Even if that means following him around all day!
Giving Perez a taste of his own medicine, Katie vowed not to leave Perez's side after he continuously followed Chloe Goodman around the house the day before.
Telling her other housemates of her plan, she said: "It's my job today to follow Perez around and tell him how annoying he is."
Unsurprisingly, Perez didn't take too well to Katie's constant chasing and bad mouthing. Before storming off to bed, he said to her: "Anything you say means nothing to me because you mean nothing to me."
She then replied: "And then you walk away. I'll just follow you, just like you followed Chloe around all last night. I'll do that to you. You're spoiling the experience for most people in here."
True to her word, Katie was right behind Perez as he made his way into the bedroom. And even though the 36-year-old tried to escape Katie by climbing into bed, she didn't stop...
"You are the ridiculous one. You are the irritant," she taunted. "You are the one that is behaving appallingly and you are the one that's making yourself look very foolish.
"You have two options... to cry, or to get yourself out of this house. I strongly advise the latter. You are the most pathetic individual I've ever seen or met, or heard of, or been obliged to spend time with in my life."
As Katie then walked away after her tirade, Perez took his chance to wind up the mum-of-three.
"Weren't you going to follow me around all day?" he asked. "Did you give up already? That's too quick! Don't be a quitter... don't be a quitter."
But to his annoyance, that only started Katie up again!
Meanwhile, it has been revealed the housemates are set to welcome a brand new arrival to the CBB house during tonight's eviction.
And the celebrity in question is heavily rumoured to be none other than Katie Price.
According to The Sun, Katie has signed a whopping £500,000 to appear on Celebrity Big Brother. So far, the mum-of-five has kept quiet on the rumours, instead telling fans she has been celebrating her wedding anniversary with husband Kieran Hayler.
If Katie is to enter the house, the 36-year-old is bound to stir things up, as she has already had previous encounters with some of this series' housemates.
After meeting both Katie and her then-husband Peter Andre in LA six years ago, Perez has said he has now grown "bored" by "her fakeness", while Katie Hopkins has criticised Katie for naming her youngest daughter Bunny.
At the time, she tweeted: "Bunny? BUNNY? Makes sense I guess, given your dad was going at it like a rabbit with all of mum's mates."
