Kat's fiance is writting his memories:

Recently it has been published that Jesse James signed for Gallery Book editorial and he's currently writting his memories. American Outlaw is gonna be released this year. Very appropiate title for a man that was been the most hated in 2010.
Besides the controversy, what he's gonna say about Sandra Bullock, her numberous lovers, and so on.., this is an indirect news about Kat since she's been the most supportive person on earth and it's quite probable that she appears on his book. It could be a "this book is dedicated to" or she may appear in a whole chapter, don't know... (source)
