Nicole Kidman opened about her family dynamics after recalling struggles to help her husband Keith Urban overcome drug addiction.

Despite previously admitting that it was ultimately up to the country music star to save himself, Kidman revealed that she's still very much the caretaker of the family along with her husband. 

She further said that Keith always used to say, "You can't save the world, Nicole. The love is abundant, and it doesn't just evaporate or disappear - it's just there."

Nicole is mother of two daughters Sunday Rose (8) and Faith Margaret (5), whom she shares with 49-year-old husband Keith Urban.

The iconic redhead also has two adopted children with ex-husband Tom Cruise, Isabella Jane (23) and Conner Cruise (21).

Nicole's comments about her maternal instincts come shortly after she revealed to People magazine that it was ultimately up to Keith to save himself from drug addiction.

Kidman added implying her personal life that it's a very big thing for people like her to go.

Keith, who has battled cocaine and alcohol abuse in the past, spent three months working on his sobriety at the Betty Ford Center just months after he wed Academy award-winner Nicole.

"It was very, very hard to have to have her go through that," he once said.

"Nicole listened to her heart and did what she felt was the right thing to do."

He further added that seeing that kind of love in action, inspires and moves him from inside and makes him want to be a better man and not a drug addict.

Nicole, once married to famous actor Tom Cruise, recently said that the secret to their 10-year marriage is to "lavish each other with love." 

Keith and Nicole tied the knot in June 2006 during a lavish Sydney wedding, before welcoming Sunday Rose in 2008 and Faith Margaret in 2011. It remains to be seen as to how Keith reacts to this situation and how the future situation will unfold.
