Katie Holmes has quietly reached what is being called a complicated divorce settlement with estranged hubby Tom Cruise, avoiding a fight that could have been the "biggest nightmare in the Church of Scientology's history," according to former Scientologist Marty Rathbun, who spoke with the Hollywood Reporter. "Katie could blow Scientology wide open,"  said Rathbun, reportedly Cruise's former mentor. At least part of Holmes' motivation for the divorce, apparently, was leaving the church. She's not the first high-profile person to walk away from Scientology. From Jerry Seinfeld to Russell Crowe, see stars who have spoken out about walking away from the sect.
