The duo rowed after Jasmine accused the So Solid Crew star of "snapping" at her. MC Harvey was shocked by Jasmine's accusations and hurt by her suggestion that he had drunk too much.
"You may have drunk a tiny bit too much tonight and maybe you don't realise I'm sensitive, but you've snapped at me twice now," said the model.
A confused Harvey replied: "Jasmine, are you thinking straight darling? I've snapped at you twice? You've got the wrong guy darling. Sorry, not me.
"I'm so confused. Snapped at you? This is so negative. 20 minutes ago, you were sat with us singing songs."
Harvey admitted that he had tried to comfort Rhian Sugden, who had been upset in the house, but claimed that it was important to make sure everyone in the house was alright, not just certain individuals.
"I've had too much to drink, that's a bit insulting. That's weird. There's other people sad in the house," he added.
Julie Goodyear, who was watching the row, told Harvey: "You're baffled. Can you imagine how the old dame feels?"
Jasmine and Rhian will battle it out in the first eviction of the series, which takes place on Wednesday night (August 23).
