Katie Holmes, Scientology: Why The Actress Filed For Divorce From Tom Cruise

Katie Holmes is divorcing Tom Cruise, her husband of over five years, and the bombshell breakup has many people wondering just what went wrong.

According to TMZ, it was Cruise's strong ties to Scientology and Holmes' fear that their daughter, Suri, 6, would get pulled into the religion that caused her to take action. Suri is reportedly at an age when the organization is set to play a bigger role in her life, and Holmes doesn't want Cruise dictating her religious beliefs.

People first reported Holmes' divorce filing Friday afternoon, with the actress' attorney, Jonathan Wolfe, stating: "This is a personal and private matter for Katie and her family ... Katie's primary concern remains, as it always has been, her daughter's best interest."

Cruise, who was reportedly blindsided by the divorce filings and Holmes' request for sole legal and primary residential custody of Suri, responded with a statement of his own, via his rep: “Kate has filed for divorce and Tom is deeply saddened and is concentrating on his three children. Please allow them their privacy.”

The news of their split even has the rumor mill working in overdrive as to whether or not Cruise and Holmes had a marriage contract in place.
