It comes as some familiar faces make a surprise return with home truths to offer.
They come back as part of a new task set in a mock bar named 'Thirsty Kirsties', based upon the set of US sitcom Cheers in which CBB housemate Kirstie Alley starred.
In one part of the task, the group are shown a clip of Natalie speaking about the housemates to Bit On The Side host Rylan Clark-Neal.
She says: "They're strong some of them, we have some weak players in there still.
"Step up Gabby. She's in the final, you made it but we've only seen her cry. We need to see her stronger. I feel like she is physically strong but is mentally weak and I'd like to see enough of the crying and being a little soft.
"I want her to really bring it, I think she can do."
Following the task, Gabby and Dan ended up rowing after he encouraged her to 'cheer up' and 'be happy'.
"You try and mug me off," Gabby claimed.
But Dan insisted he was only "having a laugh" with her. He said: "If I didn't think you were a happy person I wouldn't be spending all of my time with you so stop moaning and snapping at me because you know you can."
Remarking that his comments were just more "banter", he added: "It's what friends do."
However an unhappy Gabby stormed out of the bedroom mid conversation: "You're such a f**king smart a**e."
Currently six housemates are left in the house.
Alongside Dan and Gabby they are TV psychic Sally Morgan, Hollywood actress Kirstie Alley, Coronation Street actor Ryan Thomas and rogue trader Nick Leeson.
