Just moments after waking up, the pair bickered in the bedroom by the hair dryers.
As Sam Evans found himself stuck between the waring pair as he cycled on the bike to provide power, the girls argued like squabbling teenagers.
"You don't have to come and stand right on top of me," Hazel snapped.
"I'm not moving... shut up," Gina replied.
"Shut the f**k up" Hazel said back, with the pair's game of Shut Up pong continuing for some time.
"Have you seen yourself, look at the state of you," said Hazel, adding a bit of variety to the insults being thrown between the pair.
"Who do you think you are, you think you're so special," Gina hit back.
We're secretly hoping Hazel somehow avoids eviction tonight!
