Celebrity Big Brother housemates Luisa Zissman and Lionel Blair have had an explosive argument.
The row, in which Lionel called Luisa a "bitch", erupted after he discovered that she had broken a house rule by using mascara.
The pair then started fighting over whether Lionel had told the Apprentice star to go and get some chocolates that were later eaten.
"You told me to get the chocolates," she said. "I just went to get the champagne. So don't act all innocent and bitch about it."
He retorted: "You are being loudmouthed and think you can do what you like. But you can't."
The argument then escalated, with Dappy attempting to intervene and Luisa shouting: "Everyone will see it back. You said to me, 'Get the chocolates, get the chocolates'."

Lionel then repeatedly said: "Am I your boss? Am I your boss now?" before adding: "You are just a selfish bitch!"
"I didn't even want the chocolate. I don't even eat chocolate," Luisa replied.
When Lionel was out of earshot, Luisa added to Dappy: "He's bitching about me and Jasmine, acting all innocent. It's pissing me off."
In the garden, Lionel confided in Ollie Locke, commenting: "The thing is, she did something that not only affected me, it affected the whole house.
"That's what's upset me. It's affected you, it's affected everybody. All the people I like, it's affected - through selfishness and bitchiness."
Celebrity Big Brother continues tonight at 9pm on Channel 5.
