Although they only just confirmed that they are officially boyfriend and girlfriend, the pair have been at the centre of yet another confrontation in the Borehamwood Bungalow.
While some beef sits roasting away in the oven, Sarah, 35, is in complete disbelief when she finds out that her lover was actually trying to cook the meat for himself.
As the pair bicker about who will be eating the majority of the meat, the blonde-beauty swiped: “Would you calm down? It’s f***ing meat, it’s food. There are people out there starving, Chad.”
Clearly irritated, The Bachelorette star, 30, said: “Wait, I shouldn’t have to f***ing explain myself.
After the Girls Aloud star suggested that Chad was being slightly selfish, the reality star erupted: “Stop insinuating I don’t think of other people!”
Sarah snapped back: “Stop being so picky with your food, we have to make the most out of a bad situation.”
But the argument was too far gone to calm down as Chad raged: “Oh my god, is this a joke? Is this some type of weird tactic? What are you doing? Why the f*** are you saying that I didn’t think about other people?”
Sarah replied: “Get used to the real world because it’s not all about you,” while Chad stormed into the food store.
This follows another bust-up with Sarah and her fellow housemates who suggested she almost burned down the Celebrity Big Brother house last night.
Although she tried her best to cook a cottage pie, the star accidentally burned it, prompting Paul Danan to cry: “She’s off her rocker.”
Celebrity Big Brother airs nightly on Channel 5.
