If Sandra Bullock was hoping she had seen the last of cheating ex-husband, Jesse James, she can think again. Jesse has just signed a book deal Simon & Schuster to publish a tell-all memoir that insiders tell me will lay out why he cheated on America's sweetheart.

"Jesse has made it clear to his publisher that he has a story that has not been told yet," an insider tells me. "He wants to reveal to America once and for all that you can't blame one person when a marriage falls apart. It takes two people to make a marriage and two people to destroy one."
