The comedian beat rapper Dappy in the live final tonight (January 29) on Channel 5.
Discussing how it felt to be crowned the winner, Davidson told host Emma Willis: "It's overwhelming. All the people cheering... it's overwhelming."
He also spoke about his popularity with the public, as he was nominated by his fellow housemates nine times.
"They nominated me every time and never came to apologise to me afterwards. I wasn't playing a game," he said.
Davidson also addressed his relationship with Linda Nolan which saw them have a number of fiery rows and spats.
"It takes two hands to clap, it takes two people to argue. We're in a situation in the house where we're forced to be together, we're forced to get on.
"Linda is a fantastically strong artist. I really do admire Linda Nolan. She hasn't had the best of times, we did clash a little bit. That's what this house is about, it's very difficult in there."
The star added that he often walked away from arguments to make it easier on his fellow housemates.
He added: "If there's an argument, you take 50% of it away and the argument stops. You do it for the good of the house."
Dappy told Willis after his exit that he will call Jim his dad for the rest of his life.
"I haven't grieved for the loss of my father. When [Jim] came into my life and I met him for the first time, it's like he took that place," said the N-Dubz star.
