The pair have shared a bed and fumbled under the duvet even after it emerged Bianca wasn’t single.
But Casey says: “I don’t think Bianca and Jamie will last for long on the outside world. “I think her and CJ will stay together.
“He’s a really nice guy and they are a lovely couple. CJ must be gutted as they hadn’t split up when she went in the house, they’d been together for quite a while.
“She’s not done it on purpose to harm anyone, she’s not that type of girl.
“It’s just that when you are in the house, the outside world doesn’t seem real.”
Former CBB star Casey knows all too well how romances can blossom – she was caught up in a love triangle with Lee Ryan and Jasmine Waltz in the 2014 series.
And she explains how easy it is for housemates like Bianca and Jamie to develop feelings for each other.
She says: “When you are in a volatile house like that, you need someone to lean on.
“And things happen because there’s nothing else to do and you just spend so much time together.
“A week is like six weeks because time moves so slowly, and you find out everything about each other – it’s like one continuous date.
“You wouldn’t necessarily go for them in the outside world, it’s just who you fancy most out of who’s in there.
“You forget about everyone else and you have no realisation of anything outside the house.”
The curvy brunette also believes the All Stars have the advantage over the New Stars like Bianca as they have more idea of what to expect when the show’s over.
“It’s going to be a massive reality check for the New Stars when they come out,” she says.
“The All Stars have done it before and remember what it’s like to get back to their normal lives.
Casey says the feelers were put out for her to appear on this series of CBB but she isn’t sure she would take the risk of going on again.
But Jasmine did return – only to be evicted out of the side door – and Casey thinks it might be time the pair made up.
“I sent Jasmine a brief message when she got out congratulating her on doing so well,” says Casey.
“She wanted me to meet up with her when she went on a night out with Austin Armacost after he got evicted, but I already had plans.
“But she’ll be coming back for the finale so maybe we’ll go out for a drink and bury the hatchet – we’ve not seen each other since our series ended.
“Somehow I don’t think Lee would meet up with us though...”
In her own life, Casey is carrying on her acting and radio presenting career with several new projects lined up.
She also has a new boyfriend, whose identity she is keeping to herself at the moment.
“He’s not in the industry,” says Casey.
“And he has no interest in coming to events or anything like that, so it’s nice to keep my work and personal life separate.
“We’ve been dating for a while but made it official recently and everything’s going well. I’m very happy.”
