NICOLE Kidman's marriage to country singer Keith Urban this month will mark a new stage on her spiritual journey.

A close spiritual confidant, a Father Paul Coleman, says that Kidman's wedding preparations have helped deepen her Catholic faith.

"For Nicole, you know, this is a spiritual homecoming, coming back to the church and her faith in her old parish," he told the Catholic News Service.

Father Coleman, a Sydney Jesuit, is chaplain at the Mary MacKillop Chapel, in North Sydney.

The church has reportedly been chosen as the venue for the wedding on June 25.

It is also where Kidman attended Easter Mass with her parents, Anthony and Janelle, last year.

Since her split from Tom Cruise in 2001, Kidman has returned to her Catholic roots, attending Mass regularly.

She abandoned her faith when she married Cruise in a Church of Scientology ceremony in 1990.

Kidman has since been granted an annulment on the basis that her first marriage did not conform to the requirements of the church.

Father Coleman was instrumental in advising Kidman's family on the annulment.

But he said the family's wish was that "everything stays under wraps".

The Kidman-Urban wedding will be a star-studded affair. Guests are said to include Baz Luhrmann and Catherine Martin, Naomi Watts, Hugh Jackman and Deborra-Lee Furness, Russell Crowe and Danielle Spencer, and Lachlan and Sarah Murdoch. .

Guests have reportedly been contacted to confirm the date, and told to wait for a second secret communique to confirm the time and place.

The wedding is likely to be held at night to make things harder for photographers. Helicopter pilots, photographers, chefs and stylists retained at great expense have all signed confidentiality contracts.
