Like Princess Grace, whom she portrays in the upcoming biopic, Nicole Kidman would walk away from Hollywood for love.

"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."

"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.
