Katy Perry could be following in ex-husband Russell Brand's footsteps by releasing an autobiography.
The Sun reported that the Firework singer has signed a £2 million deal to bring out the book, called Part Of Me.
The memoir, which has the same title as her film chronicling her life on stage last year, will include her short-lived marriage and divorce from the comedy star.
According to the newspaper, it will also feature her new relationship with singer John Mayer.
A source said: "Several publishers have been after Katy for a while. She decided to go ahead so fans don't have a one-sided story when Russell publishes another Booky Wook."
