That will NEVER happen. 100% sure that's written into the prenup and divorce agreements.
I'm just about finished with the book, and now I know why Tom scaled the Burj Khalifa. Scientology gives him superhuman, godlike powers. He really believes that, according to the book. When he rescued all those people for years, changed their flat tires, etc. he literally said that only a Scientologist could do it. He said that when the COS gave him a humanitarian award for all of those good deeds.
And here I thought he did all his own stunts because he's just a daredevil with a danger addiction and/or death wish, and because he's just damn hot. Another illusion shattered. And to think I used to dream of marrying him too just like Katie. Phew. I was just a Dawson's Creek away.
