Caroline's sarcastic tone has been winding up yet more Big Brother housemates, with Sara becoming the latest to get wound up.
We saw the housemates getting angry with Caroline in last night's highlights, as she laughed her way through a dinner party.
And she caused more mischief this week as Sara recalled her trip to Egypt and the Pyramids, prompted by Luke S revealing he wanted to travel there.
But the talk was quickly taken over by Caroline, who jumped on a comment made by Sara about McDonalds in the country.
20-year-old Caroline giggled and mocked the idea of a fast food shop on a pyramid, prompting an angry Sara to hit out.
"If you're taking the piss out of me I don't think it's funny, I think it's really rude. You're such a bitch sometimes," she said.
Clearly letting out a lot of built up anger towards Caroline, Sara continued: “I don’t take the p**s out of you, so please don’t take the p**s out of me. It’s not nice.
"It really upsets me when people try to belittle me like that, it makes me feel this small so please don't do it again."
Showing all the social skills of a hermit crab, Caroline ignored Sara and continued to laugh at her own joke.
“I don’t take the p**s out of anybody. I just don’t understand why you feel the need to belittle people. It’s not nice," Sara hit back. “It makes me feel really upset Caroline.
"I was telling a story and you’re sitting there taking the p**s out of me! You’re supposed to be my friend so why are you doing that?”
Caroline had no answer, instead going on about the idea of buying a pizza from a pyramid fast food shop...
