The controversial so-called religion is rumored to have caused her 2001 divorce from movie star Tom Cruise after 10 years of marriage. And now a new book written by a Pulitzer Prize winner — not just some tabloid writer — even claims that people in the church turned Kidman and Cruise's two children against her.
But in a new interview with The Hollywood Reporter, the 45-year-old Kidman refuses to discuss the issue. When the reporter points out that an excerpt from the book, Going Clear, was recently published in THR, and that it's full of references to the high-profile Kidman-Cruise split, Kidman quickly shuts her down. "I'll bet it is," she says as she flips through the magazine. "My eye is going to a dress here — that's how interested I am in this."
Kidman's only other comments about the subject are very diplomatic. "I've chosen not to speak publicly about Scientology," she explains. "I have two children who are Scientologists — Connor [now 17] and Isabella  — and I utterly respect their beliefs."
While she's not willing to say more about Scientology, she is surprisingly game to discuss her sex scenes in the October movie "The Paperboy," in which she urinated on Zac Efron. Yeah, "High School Musical's" Zac Efron.
"I just don't find urination shocking," she explains. "I think I peed in the beginning of 'Eyes Wide Shut,' too. But then, I don't find a lot of things shocking! Violence is a lot more shocking than sex — sex is primal."
While shooting the racy scenes, Kidman notes that her director, Lee Daniels of “Precious” got into a habit of shooting her from a certain angle. "Lee had an obsession about shooting me from behind — he was obsessed with my ass! To me, that was so funny — he's hilarious, I love him," she gushes. "I'm drawn to Lee for his wild nature. I felt shy singing in 'Moulin Rouge!' — but peeing — no, not shy."
There is one thing the star vows no one will ever see her doing — although other celebrities do it all the time.
"Never would I take free clothes," she vows. "That would be so ... tacky. These people work so hard to make beautiful things — you have to appreciate that."
Kidman, who lives in Nashville with her husband of seven years, Keith Urban, and their two young daughters, is also different from most movie stars in her career choices. She tends to opt for smaller projects, rather than big-budget flicks.
"My heart is independent," she notes. "I come from Australia, I was trained in indie movies. It's an unconscious decision — it's who I am. As an actor, you live and die by your choices. I don't associate with mainstream films anymore. I don't do so well in them, either," she admits. "I guess I have a foot in both worlds. I've been offered some studio films this year and turned them down. They just didn't align with who I am."
The Oscar-winning actress doesn't seem worried about losing her Hollywood A-List status, either.
"I actually don't even know what a movie star is now — what is a movie star?" she asks. "When the best female part of the year is Claire Danes in 'Homeland,' you know the game's changed. Maybe in the '50s, there was a far more particular idea for a movie star. But now that's all blurry — everything's more fluid."
