The Girls Aloud singer first clashed with Jordan, 25, after saying she couldn’t keep up with him “bouncing off the walls all the f**king time”.
Adding that she feels left out, Sarah explained to the Ibiza Weekender star: “Me, [Chad] and Trisha call ourselves ‘The Inbetweeners’. We were in the 30s category and we’re used to being alone.”
However, the chat clearly hit a nerve with Jordan, who recounted the story to Jemma in a series of furious whispers.
He said: “She goes, ‘We’re always feeling secluded and not involved. You and Sam’s high energy makes me feel secluded.’
“She was saying, ‘You’re secluding Chad’. She was using my positivity as a weapon against me.
“I was thinking, ‘You don’t know what s**t I’ve been through’… Just because I’m positive 24/7. I’ve had s**t with my family and school,” he angrily recalled.
However, when he turned to confront the 35-year-old popstar about her comments, Jemma became involved and things became heated.
Sarah fought back: “Why are you ganging up on me?”, whilst Jemma snapped back: “There’s people s**t stirring!”
Although Jordan walked away from the argument, the 28-year-old swiped at Sarah: “You’re so f**king negative.”
The Promise hitmaker shocked when she responded: “Why you diving in like a f**king c**t?”
However, the clash was too much for Sarah, who sobbed in the Diary Room: “I can’t take much more of this. It’s really not fair. I didn’t want to come on here for this.
“They just feel because I have a fan base they feel threatened and that’s the story of my life – and they have no reason to be threatened.
“Why am I doing this? Is it really worth breaking me down again?” Sarah cried.
Now, Sarah is up for eviction after being nominated alongside Chad Johnson, Karthik Nagesan and Trisha Paytas.
