It was a verbal battle of the most brutal kind, as Dappy and Luisa Zissman got into an argument over the sexual promiscuity of men and women in Celebrity Big Brother.
The N-Dubz rapper and Apprentice star had been discussing the amount of people they had slept with in one night, and the former made it clear that a woman was promiscuous if she had intercourse with multiple partners, while a man was just a 'pig'. Dappy said to Luisa and Jasmine Waltz in the garden: 'I'd rather be a pig than a slag.'
But the fight didn't end with him walking off, as the two came to blows once more in the kitchen, where Zissman accused him of being 'chauvinistic', as did American actress Jasmine.
Dappy kept demanding to know the number of men Luisa had herself slept with in one night, and followed the businesswoman around the house to get an answer.
'Tell me how many men you have slept with in one night. That's dirty, that's disgusting,' the London-born rapper shouted. 'It's none of your business what her number is,' Jasmine said defensively.
Luisa said Dappy's mother would be ashamed of him, which only made him more irate and belligerent. That's when he brought up her daughter. 'Imagine your poor little daughter what's she going to think, if she knew the men you slept with,' Dappy accused Luisa.'My mum told me that men can't do certain things that women do, and women can't do certain things that men can do.'
The argument had taken them into the bedroom, where Luisa tried to end the discussion by insulting his intelligence: 'I can't deal with someone of your intellect and IQ.'
'What IQ you talking about,' Dappy spat out. 'I got an A+ in English, you got an A in being stuck up.'
But the verbal battle still went on, moving back into the kitchen, and that's when Luisa really lost her temper.
'Quit following me around this fucking house,' she shouted. 'Fuck off! You're harassing me.'
She added: 'Your agent knew to tell you to keep your mouth shut, as soon as you open your mouth, you'd act like that, and you told me that.'
Dappy retorted: 'You're a two-faced slag!'
And Luisa was just as derogatory in her response: 'I think you're a fucking prick, a wannabe fucking child who thinks he's a gangster.'
However the fight ended with the rapper reiterating his first point: 'If a man sleeps with five women he's a pig, and if a girl sleeps with five men well you know.'
Apparently everyone does now, Dappy.
