Nicole Kidman's Kids Don't Spent A Lot Of Time Together

Nicole Kidman admits her four children have an ''interesting dynamic.''

The 'Grace of Monaco' star has daughters Sunday, five, and Faith, three, with husband Keith Urban, and 21-year-old daughter Isabella and 19-year-old son Connor with ex-husband Tom Cruise, but they don't spend a lot of time together.

The 46-year-old actress told The Sunday Times' Style magazine: ''When you have adult children and then tiny little ones, they don't spend much time together. A 21-year-old doesn't have much in common with a three-year-old, but it's an interesting dynamic.''

The Oscar-winning actress, whose youngest daughter was born via surrogate and eldest children were adopted, would love to have another child in the future.

She said: ''I would be down on my knees begging for another one, but that's not going to happen. Even though I got a call from my publicist recently, saying, 'Are you having another baby?' And I said, 'I wish'.''

But Nicole is very happy with her family and says she and Keith still have great ''chemistry.''

She said: ''I have the husband that I'm so grateful to have. I have my soul mate and probably because he's Australian, that has a lot to do with it.

''We were born in the same year [1967], we have all the same references, be it music or just life in general. But I think it's really about chemistry -- you either have chemistry or you don't. And I'm lucky to have it with him... whether it's a common nationality or just pheromones. Whatever it is, it all works.''
