The pair's history was revealed when they both entered the CBB house on Tuesday night, which led many to predict major awkwardness and fireworks to come.
So far that hasn't happened – but it's only day two.
On last night's show, however, viewers saw Christopher admitting that he still cares about Danniella and considers her a close friend despite their past rows, suggesting we could see a reconciliation.
Christopher spoke in the Diary Room after Danniella sent herself to The Box to ensure the other housemates had beds for the night.
"The last time we spoke was last March, it was nearly a year ago. I was expecting it to be a little bit awkward and it has been but it's been alright and I just feel a little bit lost now she's gone next door."
He went on to say: "Whatever has happened on the outside, let bygones be bygones. Whatever s**t people have made up to cause trouble between us let's leave it at the door and let's get on with it. Obviously we are still going to talk about stuff like that but for now it's going pretty good.
"I do still love her, like. She's is a still a good friend of mine."
Former X Factor contestant Chris had previously said: "I don't hold grudges. She fell out with me. When she split up with her partner, he was still trying to be my friend. I struck up a friendship with him and I was caught in the middle. I think she thought that I took his friendship over hers, but it wasn't like that.
"I don't hate her. It's just that we haven't spoken. She was patron of my academy, we did panto together, I've looked after her, but I've not had the chance to speak to her about everything because she changed her number."
Chris went on to say it would be awkward seeing Danni again, but added: "Yeah, but there's nothing I can do about it. I don't know how it's going to be. I'll just be polite. It's hard, because as I say, I've not done anything bad. If I had I would feel guilty but I've not so I've got nothing to worry about."
Meanwhile, former EastEnders actress Danniella has vowed to not cause trouble with Chris in the house, but says that doesn't mean she likes him.
"I don't talk to Chris. It's not tricky for me at all – I shall be polite for the sake of the show. I'm not going to get into the reasons of why we don't talk. But I'm not interested or getting into an argument. If he tries to start an argument I'll say 'I'm not interested, I know what you're trying to do, I'm going for a cigarette'.
"I won't be bullied into trying to talk about something or trying to make the peace. I'll say to him 'I will get on with you, we can have a really good laugh while we're in the house, because we've got to live together'. At the end of the day it's not the time and the place to discuss things. I would never make it awkward for anybody else, that's the worst thing somebody could do."
