Did you know that a Scientologist played matchmaker to Tom Cruise and Katie Holmes? Shelly Miscavige, wife of Scientology chairman David Miscavige, reportedly went on a hunt to find love for Cruise after his second divorce, from Nicole Kidman. The result of Shelly Miscavige's matchmaking? The 2006 wedding of Tom Cruise to Katie Holmes.

The wedding was everything the couple could have wanted, with Shelly playing cupid and Cruise's best friend, David Miscavige, standing beside him as his best man. But a year later everything changed when Shelly Miscavige disappeared without a trace.

Helping Cruise hadn't been Shelly's idea. The New York Post reports that Cruise, lovelorn after his breakup with actress Penelope Cruz, had turned to David for help in finding a new wife. But the diminutive church boss, who has a notoriously volcanic temper, became irritated with Cruise's constant calls; as the head of a multibillion-dollar operation, he felt it was beneath him to be seeking women for the Hollywood star. So he deputized Shelly to take over the task.

What happened after the ill-fated wedding to make Shelly Miscavige disappear? Take a look at three theories on her disappearance below:

The Hole - Business Insider reports that Shelly may be in The Hole, a mysterious group of buildings that are rumored to be where misbehaving Scientologists are held captive. While the church denies the existence of The Hole, Shelly reportedly misbehaved just before her disappearance. It was reported that she filled job vacancies without the permission of her husband.

It has been reported that anywhere between 80 and 100 people reside in The Hole. Those who have fallen out of the organization's good graces reportedly are required to do group confessions all day and all night. Would this lead her to be locked up in The Hole?

David Miscavige's "violent tendencies" - It has been reported by some Scientologist church members that their leader has had some violent tendencies. Many admitted that they had witnessed beatings, or had been beaten themselves, at the hands of David. Is it possible that Shelly Miscavige suffered a horrible fate at the hands of her husband?

Claims - The Daily Mail reports that many believe Shelly went into hiding after becoming disillusioned with the religion. Another theory circulating on her disappearance is that she died after a battle with cancer.
