Well, not even that, really.
While the pair were seen kissing after Friday night's final they've not been together since and now it's been claimed it's all over.
A source told The Sun newspaper: “They are going to remain firm friends but Jamie needs to spend time with his family first and focus on other things in his life.
“They had a great time in the CBB house but unfortunately it has come to an end.”
Despite being so loved up in the house that they couldn't keep their hands off one another, Bianca and Jamie apparently didn't ever meet up following the final.
"Jamie was surrounded by girls at the club – Bianca looked like the last thing on his mind," an onlooker told the tabloid “He was out till the early hours after watching Drake at the O2 for a second time and wasn’t quick to bat off any attention at the club.
“Bianca was at her gentleman’s club The Gaslight just a few miles away but the pair remained apart.”
Speaking about his romance with Bianca after leaving the house, Jamie insisted it wasn't just for the cameras.
"Bianca is amazing. She wouldn’t do anything for fame, she doesn’t need to," he explained. “What we had in there is 100 per cent genuine. I’m going to sit with her over the weekend and see what she wants.
“She was definitely someone I could fall in love with.”
