Uh oh—we've got some bad news for Katy Perry. Ex-husband, Russell Brand, plans on writing a tell-all book about his 14-month marriage to the "Firework" singer. Besides writing about his recent marriage that went sour, Russell will also reveal information on his sex addiction and drug problems.
What else do you think Russell will cover in his autobiography? Tell us in the comments below or send us a tweet @OKMagazine.
