Taking this rumor further, I've also heard that Scientology has offered "contracts" to the women in his life - Nicole and Katie. It was speculated that Nicole was given a "10 year" contract and Katie a "5 year" contract wherein they would agree to marry him to serve as a "wife" and he would in turn further their careers. Don't know if that is true either, but did find it interesting that he and Nicole ended their marriage right at the 10 year mark.
Also, Nicole's career certainly took off after becoming Mrs. Cruise. Let's see what happens with Katie's.
Rumor also has it that prior to Katie, Tom was interested in Kate Bosworth, who turned down a meeting with him. Good for her!
