Despite being given an exercise machine tonight, Marco and Nadia have proved they'd rather give their wicked tongues a work out than get sweaty on a cross trainer.
Both housemates are blatantly very fond of each other, but boy, they do like to get their claws out.
"Did you enjoy the impression of you, Marco?" asked Nadia, not so innocently, of Dan's performance as Marco in tonight's task.
Marco said he did, none too convincingly. "It's nice how each of us brought out our true qualities," he said. "Like the dirty slut and lesbian."
Nadia jokingly protested she was not in denial about lesbianism - while glossing over the dirty slut insult - prompting Marco to call her a lesbian bitch. Which was nice.
Following Nadia into the bedroom Marco interrupted her taking off her bra. "I don't know why you had a bra on when you've had them out ever since you came here," he hissed.
And later Michelle playfully asked Marco why he didn't "get it on" with Nadia. "Darling! I've seen more attractive women who were pensioners," he smirked.
We bet there are plenty more where that came from...
