'Big Brother' housemates Nikki and Grace have clashed over the household chores, with Nikki criticising Grace's cooking skills.
The row broke out after Grace and Richard cooked a salmon dinner for the housemates. Nikki picked at the food before saying that the salmon was a "bit dry".
When Grace muttered some obscenities about the remarks, Nikki said: "I'm sorry Grace, but I'm upset. I didn't realise the salmon meant that much to you."
"Stop moaning, you're like a child," Grace replied. "You're 24, I'm 20. And I cook and clean. It's not a hotel. It wouldn't be so bad if you washed a dish once in a while."
After several of the other housemates joined the argument, Richard advised Nikki to go have a "lie-down", causing her to storm out of the kitchen in tears.
Later when Pete tried to make peace in the house, Nikki told him: "I've never met a more vile creature than that, she's the most vile thing on this earth."
"I can't be here when she's here. She's Miss Perfect. I can't take on the whole house, she's got five of them on her side. I'd love to see her vanish in a puff of smoke."
Speaking to Lisa, Grace later said of Nikki: "I hate two-faced people, she doesn't like it if she's not the centre of attention."
