Sarah Harding and Chad Johnson may have only been official for a day, but the couple have already had their first argument - and it's a meaty one.

In scenes airing tonight on Celebrity Big Brother, Chad is left irritated after Sarah asks him whether he wants some of her meat.

He is not impressed, and asks her: "Are you playing the American reality TV card right now?"

"No I'm f***ing not," she says before quipping, "Would you like some of my meat?"

He snaps: "Go f*** your meat."

Taken aback by his annoyed tone, she says: "We were having banter for f***'s sake."

"That wasn't funny," Chad insists. "I was insistent upon wanting to cook a tiny portion of meat."

She tells him: "Would you calm down? It's f***ing meat, it's food. There are people out there starving, Chad."

"Wait, I shouldn't have to f***ing explain myself," he says irritably.

Sarah tells Chad that he is being selfish

"No you shouldn't," she agrees. "So calm the f*** down. You can eat anything in this room but just make sure there's enough for everyone and consider other people.

"You need to think about other people."

Chad explodes: "Oh my god, stop saying that an insinuating that I don't think about other people!"

"Well you didn't," Sarah interjects, irritating him even more.

"Yes I did!" Chad says before putting his head in his hand. "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?"

She continues to tell him to calm down and he gives up.

"Can't you just eat what everyone else does and stop being so picky?" she asks him.

"We're not in a normal situation, Chad, and we need to make the most of a bad situation."

"You're totally right," he says sarcastically.

"You're totally being selfish right now. You're being selfish, " she says as he continues to be sarcastic with her.

He then sulkily says that he won't eat any meat now.

As he leaves she tells him: "You need to get used to the real world because it's not all about you."

Celebrity Big Brother returns tonight at 9pm on FiveSTAR.
