The singer told The AP that her latest record shows that she has matured since the release of her first album.
"It's really validating, but not in like a mean girl's kind of way feeling," she said. "I've always believed in myself and it's just wonderful that people can finally jump on the train and be a part of something really exciting."
Perry added that she feels particularly proud of the track 'Circle The Drain', which is about a man whose drug use destroys his relationship.
The 'I Kissed A Girl' musician explained: "It was difficult to write it because it's not where I am now, but it was a feeling that I had stored away a long time ago, in my emotional filing cabinet."
The star also stated that she intended her new album to cover a range of emotions that she has gone though over the last two years.
"Sure, I wanted to make a record with more tempo, but I didn't want that to mean that I had to write about just DJs and dancing and getting drunk… I need a soundtrack for all the rest of my emotions, and that's what I really wanted to provide with this."
Perry further noted that Teenage Dream is more important for her career than 2008's One Of The Boys because it shows her maturity as an artist.
She said: "This record is going to kind of solidify the fact that I have something different to offer, a different perspective."
