Katy Perry Admits She Would Never Write An Album Like Adele's '21'
The 'Firework' star says she is "in a good place" following her marriage breakdown.
Katy Perry has confessed that she could never write an album such as Adele's '21' because she couldn't devote a record to her heartbreak.
The 'I Kissed A Girl' singer told The Sun newspaper that she is looking forward to the future and insisted she is in "a good place".
"I'd never devote a whole record to heartbreak," she revealed. "I'm happy, I'm in a good place, I'm looking forward to my future.
The American star, who releases her new movie Part Of Me 3D in cinemas today (5th July), is seen enduring the strains of her marriage breakdown on tour during the film and told the publication that her hectic schedule ultimately lead the split with comedian Russell Brand.
"If I could edit it any other way I would, but that is exactly the way it was," she said. "I always had plans to make this record and usually with a record, you tour a record.

"Touring is always important to me. It's like a big IOU to my fans, because I know they are the reason I exist."
The star has vowed to go into hiding when she finished the promotional schedule of her film and has already promised her lyrics will most likely get "darker" on a new album.
Katy spoke to Capital at the premiere of the new flick and revealed that she is hoping good friend Rihanna and also Prince Harry will go down to see the movie.
