Nicole Kidman and Keith Urban and their daughters

Nicole Kidman's family keep her "pretty sane."

The 'Railway Man' star, who has daughters Sunday Rose, five, and Faith Margaret, three, with her husband of seven years, Keith Urban, works "very hard" to make sure her children have normal lives and credits them for keeping her grounded.

The 46-year-old actress told E! News: "There's a goldfish and a bunny. It's a completely normal life, which is what we both work very hard to have for our children. And I know normal has 100 different definitions these days, but what I consider normal is just really kind of eating dinner together, having breakfast together, talking, hanging out, going to moves...just the normal stuff.

"I mean, there's nothing like after dinner going, 'Hey, you wanna go get ice cream?' and the excitement of going with a three year old and a five year old to go and get ice cream. That, to me, is an awesome Saturday night."

The Australian beauty, who also has daughter Isabella, 21, and son Connor, 19, with her ex-husband Tom Cruise, usually travels everywhere with Keith and their daughters.

She explained: "I think we're a gypsy family and we travel around a lot and as long as I have my husband and kids close then everywhere feels pretty safe and pretty sane. I come from a family like that and we've created our family now to be like that."

She added: "Luckily Keith and I are very, very close and our kids are very close, we're just a very tight little unit."
