How Nicole Kidman stays in touch with her kids with Cruise, Isabella and Connor

Nicole Kidman is all about the Internet and technology -- but only when it comes to her children.

In a new Q&A with DuJour, the 48-year-old actress says she used more modern forms of technology to stay in touch with all of her children -- including 22-year-old Isabella and 20-year-old Connor, her two kids with her ex-husband, Tom Cruise.

"I have four children, so to stay in touch with them is very important," Kidman says, also referring to her two daughters with Keith Urban, 7-year-old Sunday Rose and 4-year-old Faith Margaret. "I'm definitely engaged in it but I don't let it rule my life."

Kidman has been tight-lipped about her two eldest children in past interviews. When pressed by The Hollywood Reporter in 2012, she explained, "I've chosen not to speak publicly about Scientology. I have two children who are Scientologists -- Connor and Isabella -- and I utterly respect their beliefs."

    However, she did gush about them to Women's Weekly last May, praising the two for being "generous, kind and hardworking."

    "And these are traits that I love to see in my children," she added.
