It seems that Tom Cruise is a perfectionist when it comes to his work AND his home life!

The Jack Reacher star, 50, steers a tightly run ship when it comes to his palatial Bel Air estate, a well placed source says, telling Breaking Celebrity News exclusively that the actor controls his household staff's access around the home by creating specified 'zones' and restricting them from entering areas that they aren't assigned to work in.

"Tom runs his household staff with absolute military precision and with the utmost attention paid to security," the source says. "His Bel Air mansion is divided into zones, meaning that housekeepers and other support staff that work in the kitchen and food preparation area, aren't permitted to go into another area of the house that falls outside of their allocated zone.

"It's a huge house and Tom does this to ensure the safety of his family and children when they are visiting. The only members of household staff that have access to the entire house is the estate manager and the head of security."

The source goes on to divulge that when it comes to catering to the every possible need of those closest to him, generous Tom does not hold back!

"When Tom and Katie were married, Tom hired her a personal valet who would take care of wardrobe, scheduling and other needs. Tom also provides and pays for personal valets for his mom and sisters."

As Breaking Celebrity News previously reported, when Tom and Katie were looking to hire a new estate manager, prospective staffers had to undergo rigorous testing at the Scientology Celebrity Center in Los Angeles.
