Nicole Kidman is among the more private celebrities we have today. That's not to say that she's rude or stand-offish, she just likes to keep her personal life as closed off from her public life as possible.
Kidman and husband Keith Urban do have two daughters, though. Their eldest, Sunday Rose, is 11, and their younger daughter, Faith Margaret, is eight. Kidman and Urban are usually especially guarded when it comes to their children, and with good reason given the impact that the spotlight can have.
