Ryan Thomas appeared on the verge of tears during a TV interview on Wednesday as he was shown footage from the Roxanne Pallet 'punch' allegation aftermath.
The former Coronation Street star, 34, was visibly choked up and struggled to speak for a few seconds on Channel 5's Jeremy Vine after watching film of himself breaking down in the diary room.
It showed him visibly distressed and in tears after learning Roxanne had accused him of punching her during a play fight.
After the footage played, the camera panned back to Ryan in the studio; he was silent for several seconds and cleared his throat on multiple occasions as he tried to speak.
He finally said: "I've not seen any of that back. I haven't seen anything. It's strange."
You just want your friends and your loved ones with you when something like that happens.
Ryan was asked whether he genuinely expected police to be waiting for him after the accusation.
He replied: "At the time it was all going on it was something that crossed my mind. You're cocooned in there, you don't really know what's happening."
He continued: "It caught us all by surprise, especially myself. That house, when something like that happens, can become very isolated. I know it did for me, personally. But as it unravelled it was just nice to have your fellow housemates support you. That's how it felt.
"You don't have any idea what's going on when you're in there. You just want your friends and your loved ones with you when something like that happens."
Ryan said viewers don't understand what it's like being in the Big Brother house, calling it "tedious" as there is no sense of time.
"It's tedious, there's no element of time, the boredom, everything is heightened in there," he said.
"Situations are heightened. Evictions and nominations become a horrible thing because you end up having to bitch behind people's backs and I hate that.
"I know it has to happen, we know what we're doing when we do that show."
Ryan was also played footage of Roxanne's apology.
He said he appreciated Roxanne saying sorry but didn't want to dwell on the accusation as he'd rather look forwards to a positive future.
"Listen, I think that Roxanne has been through a lot," he said. "Big Brother makes headlines and sometimes for the wrong reasons, and I appreciate Roxanne's apology.
"I think it's time we move on and look forward and not dwell on the past. Because I think she's suffering enough, and I don't want to be a part of that."
Ryan emerged as the Celebrity Big Brother winner on Monday night, beating runner-up, Hollywood actress Kirstie Alley.
He told Emma Willis in his exit interview that he'll forgive Roxanne if it's what she needs to feel better.
"For me, I have the best network of family and friends. I have the best mates in the world. Some are here today. That's what is important.
"If this person has an issue and a misunderstanding who am I to sit here and judge? Forgiveness is a big thing and this place is a horrible place if you get it wrong and I don't personally want to be part of that.
"So, if she wants forgiveness and it makes her feel better, then I would rather give her that because I think she's been punished enough by the public and the people around her."
