Katie HolmesAt the time of pregnancy when most soon-to-be-mums are (or at least really want to be) permanently sat down with a cool drink to hand, Katie Holmes is apparently spending eight hours a day at the Scientology headquarters.

The Sun is reporting that Katie is visiting the church up to three times a day.

“Her family are becoming very worried,” a friend has revealed. “They don’t know what she is being taught.”

“She is becoming more distant and seems to worship Scientology as much as she worships Tom.”
