Kidman, who married Cruise at age 23, was immediately swept into a whirlwind of overwhelming fame, with the world demanding to know every detail about the couple's union. The actress said that that attention and pressure brought the pair closer together for a time, because they were both dealing equally with the same demands.
"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," Kidman told the magazine. "And there is only one other person that's 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."
Still, Kidman said that she "was so young" at the time of their union, and that it was her second marriage to country star Keith Urban that led her to "[her] great love."
"I really did not know if that was going to happen," Kidman admitted to the magazine, reflecting on the uncertain time following her sudden split from Cruise. "I wanted it, but I didn't want it for a while, because I didn't 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. And I needed to grow up."
