Katy Perry Wrote 'Wide Awake' As 'Perfect' End To Teenage Dream Era

'I love this song so much,' Perry says in 'MTV First: Katy Perry' exclusive interview.

Katy Perry was on a mission when she sat down to write her new single, the dreamy ballad "Wide Awake." Full of imagery about moving on from a tough situation, according to Perry, the song is the perfect way for her to end her Teenage Dream era. It is also a track she wrote specifically for her July 5 movie release, "Katy Perry: Part of Me."

"I love this song so much," she told MTV News. "It was a song that I hadn't written for Teenage Dream. I was doing this movie and they asked me if I wanted to write an end-title song for the movie and I was like, 'I know exactly what I want to say.' I was really kind of dying to write another song at that point. I didn't want to wait until I did a whole new record, and it's kind of the perfect last word of me at this moment."

Katy will have a lot more to say about the track and its video when she opens up about it all during a special MTV News interview, "MTV First: Katy Perry," airing on Monday. Perry said about the clip, "I just wanted to tell a story about myself going through this journey, maybe sometimes trying to get out of the maze. There's good parts, there's bad parts. Of course, there have been a lot of things that went on last year that I had to get through and overcome. I think what probably kept me going is just the purity of my belief in music."

Make sure to tune in to MTV this Monday, June 18, at 7:53 p.m. ET, for the world premiere of "Wide Awake," followed by an exclusive 30-minute interview with Katy and MTV's Sway Calloway on MTV.com. Perry will discuss the song as well as her upcoming 3-D concert film, "Katy Perry: Part of Me."
