Nicole Kidman covers the December issue of Vanity Fair, and the 46-year-old actress compares her marriage to Tom Cruise to Brad Pitt and Angelina Jolie's highly-publicized relationship.

Kidman tells the mag:

    "There is something about that sort of existence that, if you really focus on each other and you're in that bubble, it's very intoxicating, because it's just the two of you. And there is only one other person thats going through it. So it brings you very close, and it's deeply romantic. I'm sure Brad and Angelina have that -- because there's nobody else that understands it except that person who's sleeping right next to you."

Kidman and Cruise got married in 1990 when she was just 23, and they split in 2001. Despite the fact that they made it work for over a decade, Kidman confesses that she was "so young," and added, "with no disrespect to what I had with Tom, I've met my great love now," referencing Keith Urban, whom she married in 2006. "And I really did not know if that was going to happen. I wanted it, but I didn't want it for a while, because I didnt want to jump from one relationship to another. I had a lot of time alone, which was really, really good, because I was a child, really, when I got married [to Cruise]. And I needed to grow up."

Following her split from Cruise, Kidman says she was able to relate to suicidal author Virginia Woolf, whom she played in The Hours. "At the time, I was at a low point, and by playing her, it put me into a place of appreciating life," she said.

Kidman and Urban now live in Tennessee with their daughters Sunday and Faith, and she says life is now "very, very peaceful," adding, "Theres an enormous amount you have to give up if you want to have a family. You can have a certain career, but you cant be living in Hollywood, [where] absolutely everything, everything revolves around it," she reveals. "That wasnt my choice. Id rather revolve around somebody elses career and then still find my own."
