Before she was happily married to Keith Urban, Nicole Kidman welcomed two children in her life with then-husband Tom Cruise.

Now, Kidman is breaking her silence on their two adopted children, Connor and Isabella Cruise, of whom she rarely speaks publicly.

"I'm very private about all that," she said in a new interview with celebrity magazine Who. "I have to protect all those relationships. I know 150 per cent that I would give up my life for my children because it's what my purpose is."

Kidman confirmed that Bella, 25, and Connor, 23, are both practising Scientologists like their father.

"They are adults," Kidman said about their faith. "They are able to make their own decisions. They have made choices to be Scientologists and as a mother, it's my job to love them."

She added that she considers her role as a mother is to "always offer unconditional love".

"I am an example of that tolerance and that's what I believe – that no matter what your child does, the child has love and the child has to know there is available love and I'm open here."

Kidman, who will be returning to Sydney with Urban later this month when he hosts the ARIA Awards, is also the mother to Sunday, 10, and Faith, 7.

In May, she revealed in an interview that one of the reasons she and Cruise did not have any biological children together was that she had a miscarriage early into one of her pregnancies.

"From the minute Tom and I were married, I wanted to have babies," Kidman told Marie Claire magazine in 2007. "And we lost a baby early on, so that was really very traumatic."
