Kidman's marriage to Tom Cruise between 1990 and 2001 often made headlines.
The relationship, which came on the heels of Cruise’s divorce from Mimi Rogers, was catnip for the tabloid media.
In a new interview with Harper's Bazaar magazine, Nicole was asked about what she thought of the press focusing so heavily on her relationship with her ex-husband.
She replied: "I was young. I think I offered it up?"
Nicole continued: "Maybe I've gotten a bit more trepidatious, but I'm always trying to be as open as possible. I just prefer to live in the world that way…
"I'm wary at times, and I've been hurt, but at the same time I much prefer a warm approach rather than a prickly shut-down approach. "
