> Katy Perry: 'My music is about to get real f**king dark'
After seeing a clip of her work, she said: "It's been an incredible journey this past second record and also the deluxe - well the special edition, we can't call it a deluxe can we? - version of Teenage Dream.
"I saw why I'm so exhausted - I like working so hard. But it's really so fun to work so hard because I love reaching my goals. I do a lot to sell my records. I work very hard. I like to sell out in all the best ways."
She added: "I swear after this song, I'm taking a f**king vacation."
Perry, who divorced Russell Brand in December, will release 'Wide Awake' as the final single from Teenage Dream.
She became the first female artist to achieve five US Hot 100 number ones from a single album last year. 'Part of Me' topped the Billboard Hot 100 in February.
