However, her last few days in the house saw her arguably get close to fellow housemate Lewis Flanagan, and the reality star has admitted their bond may have gotten stronger if she survived longer.
"I think if I had stayed there a bit longer we would have got a lot closer," Isabella told Digital Spy. "We were finally getting a bond, only literally, it blossomed the last couple of days.
"His guard finally came down. He trusted me and we were really getting on, but I can't really say. But I would like to see him when he gets out of the house."
During her time on the show, Isabella was also caught up frequently in clashes between Lewis and the now-evicted Hussain.
Explaining the situation, she said: "I think it was because Lewis was getting close to me. Or we were getting close. I think that created the problem."
Isabella's eviction came as a surprise twist, with the richest housemate Cameron deciding her fate instead of the public… and she's not very happy about it.
"I don't think it was fair at all," she told us. "I think I would have been there a lot longer if it wasn't down to them. I really don't feel like it was fair. It's like it hit home now. I'm really, really, really, really gutted… I don't think I should have been called tonight."
Isabella added: "Relations were starting to blossom and I was starting to feel comfortable, and I've gone. I'm just so upset that my stay in the house was put down to them and not to the public. I feel as though Cameron's decision was maybe more jealousy than genuine."
