Katie Holmes is allegedly "freaking out" about her daughter Suri learning more about Scientology.

The actress-turned-designer divorced Tom Cruise last year. Holmes won sole custody of their six-year-old child Suri, with Cruise granted regular access.

One of the causes of their relationship breakdown is alleged to be Cruise's Scientology faith, which Holmes reportedly does not want Suri involved in.

Due to his filming commitments, Cruise has spent little time with Suri since June last year.

However Cruise's' latest movie All You Need Is Kill is scheduled to finish shooting in March, after which he'll see his daughter more. It has been claimed Holmes is anxious about the change as she is still worried about Suri being around the controversial religion.

"This worry has been hanging over Katie ever since she and Tom split up last summer, and now it looks like her fears are about to become a reality," a friend revealed to British magazine Grazia. "It's really freaking Katie out. One of the terms of the divorce was apparently that Tom is not permitted to give Suri a Scientology-based education."

Adding to Holmes' growing concerns is Suri's seventh birthday which falls on April 18.

In Scientology, it is around a child's seventh birthday when "sec checking" starts. This is a process of tough questioning during which the youngster is wired up to a lie detector machine.

"Tom is psyched that he can now spend more time with his beloved little girl, and of course Suri is super excited too - she adores her daddy," a friend continued.

"[Meanwhile] Katie is worried that Suri might still be subjected to a Scientology 'sec checking' process, where young children are audited for the first time."
