Katy Perry has reportedly signed a $3.2 million deal to write an autobiography.
The I Kissed a Girl hitmaker's book is set to be called Part Of Me, the same title as her 2012 concert film, and will cover her career and personal life, including her relationship with ex-husband Russell Brand and current romance with John Mayer, according to Britain's The Sun.
A source tells the publication, "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."
Brand has written two autobiographies; 2007's My Booky Wook and its 2010 follow-up, Booky Wook 2: This Time It's Personal, which was dedicated to Perry. The funnyman filed for divorce from the singer in late 2011 after 14 months of marriage.
