'I was really ­impressed': Katy Perry inspired by Taylor Swift to make tell-all documentary

Katy Perry has been inspired by Taylor Swift to create a documentary about the "juicy" chapters of her life and career.

The 'Chained to the Rhythm' singer has revealed she's been collecting footage from the road since the release of her 2017 album, 'Witness', and she's gradually building up each chapter to form a future film.

As per the Daily Star newspaper's Wired column, Katy said that the "'Witness' time of [her] life is just one chapter in a very large book that is yet to be finished".

It was seeing former rival Taylor's Netflix doc 'Miss Americana' which inspired Katy's decision.

Katy stated that she was "really ­impressed" by Taylor's documentary, especially since it wasn't just focused on "one tour or one record cycle."
