The reality star was voted out during tonight's live final ahead of champion Paddy Doherty.
Katona left the house to the sound of One Direction's 'What Makes You Beautiful' to a very positive reaction from the crowd.
She told host Brian Dowling: "I can't believe it for one second. Thank you so much, I can't believe it.
"In my whole celebrity career, I never thought I would have a chance to put my wrongs to right. This show has helped me do that."
She added that she had made "solid friends" in the house, especially winner Doherty. She said: "That man helped me every single day. He said 'forget your past', that's what I've done."
When asked if she was going to feel "pressure" after being given a "clean slate" from the series, she replied: "I'm not going to feel pressure. I've been there, done it, I've bought the T-shirt."
On the subject of flirting with Lucien Laviscount, she said: "Lucien's like my brother. I kiss everybody on the lips. I hug everybody. I'm very affectionate."
Kerry Katona finished ahead of previous evictees Bobby Sabel, Darryn Lyons, Lucien Laviscount, Amy Childs and Jedward.
