Katy Perry Unveils Fairy-Tale Inspired 'Wide Awake' Promo
Watch the final chapter of K-Pez's Teenage Dream album here...
Speaking of Wide Awake, the 27-year old told MTV News: "Well, this song, I have a lot of different emotions and feelings in all of my songs. This song in particular is a dose of reality. It's kind of like coming down from a high.
"You've been on cloud nine for so long, and it can't always be so sweet and sometimes you need to realize that, and you have to pick yourself up and move forward and face the facts of life and know that this is just a lesson you learn and you're stronger because of it."
Wide Awake is the final chapter of the fairy-tale that was Katy's Teenage Dream years, and is due for release in the UK on 2nd July.
