The pair clashed over Dappy's apparently sexist views, with Jasmine Waltz siding with Luisa and branding N-Dubz star Dappy a "bigot."
Luisa ranted at him: "You sound like you're a sexist, male chauvinistic bigot.
"Your mum should be ashamed with your attitude to women, I bet she'd be absolutely disgusted and I think the nation watching this now would be in complete agreement with me."
Dappy retaliated by taking a swipe at Luisa's supposedly rich upbringing, saying: "You ain't be through nothing mate, you're stuck up, I had to work for it all."
This however seemed to only rile Luisa up more who angrily called Dappy "rude" as she shouted at him: "How dare you put woman down."
As other housemates stepped in to cool down the increasingly heated argument, Luisa continued to vent: "When he walks out of here and watches what he said he'll regret it.
"It angers me that he's classed as a role model, him of all people in the world. A f**king child who thinks he's some bad boy gangster."
