The popstar told The Mirror that she has not given up on love or British men, despite the pain of her divorce.
Perry said: "I'm moving forward one step at a time. It was a year I'll never be able to recreate. It had amazing highs and some big lows, but that's life.
"I've learnt I'm in a very modern fairytale but I also know I don't need the Prince Charming to have a happy ending."
However, the 'California Gurls' singer added: "I still believe in love, most definitely. [And] I still like London boys", before clarifying: "Except one."
Perry has consistently defended her decision to keep footage filmed during the split in her documentary Katy Perry: Part of Me.
"There were things that made my tummy turn when I saw them because I had already lived them and really didn't want to live them again," she told the paper.
"But I thought maybe if I showed I got through the problems, other people wouldn't feel so alone.
"The whole movie is about me overcoming obstacles... my upbringing, the guys in suits from the record labels and then my personal struggle, going through it and landing on my feet.
"The message is pretty simple - it's 'be yourself and you can be anything'."
