"If it were the choice between my family and Keith, and my career, I wouldn't even bat an eyelid," the 46-year-old actress told The Australian Women's Weekly. "The most important things to me are the love of our relationship and my children."
Kidman is the mother of young daughters, Sunday and Faith, with husband Keith Urban.
"At this stage of my life, and with time being so precious, the joy I get from us as a family outweighs any joy in any other area of my life, by far," she said in the interview.
As for her two eldest children, Bella and Connor, with ex-husband Tom Cruise, Kidman spoke with pride about the adults that they have become.
"They are generous, kind and hardworking," Kidman told The Australian. "And these are traits that I love to see in my children."
