Katie Holmes’ divorce filing came out of the blue, both for the public and her now ex-husband, Tom Cruise. However, the lengths Holmes went to in order to keep her plans hush hush were anything but hasty.

Holmes broke the news to Cruise that she was filing for divorce on June 29, on a phone call while Cruise was thousands of miles away in Iceland, shooting his upcoming sci-fi film “Oblivion.”

In just a few days, it seems as though Holmes filed for divorce, took off to a New York pad with the couple’s six-year-old daughter, Suri, and rid herself of the name Mrs. Cruise. But the former “Dawson’s Creek” starlet put careful thought into her master divorce plan.

According to the Los Angeles Times, a friend of Holmes provided her with a disposable phone so she could communicate with her New York City divorce lawyers so the public – and Cruise – wouldn’t know what was going on.

Holmes, 33, had allegedly been planning the divorce for some time, even informing her parents of her decision to split from the 50-year-old “Rock of Ages” actor, whom she had been married to for five years.

Perhaps Holmes’ biggest advantage was that she had her own father, Martin Holmes, a top Ohio divorce lawyer, on her case, vying for her every step of the way.

The ex-couple settled quickly and obtained the divorce on Monday. Although not much is known about the specific details of the settlement, Holmes, who requested sole custody of Suri, will have total control over her daughter’s education.

And after renouncing her Catholic faith for Cruise’s Scientology, Holmes’ has now taken her life back and registered at the Church of St. Francis Xavier in New York. Presumably, she will be raising Suri Catholic as well.
