The Big Little Lies actress was sporting a pretty white sundress and even took to Instagram to boast about her date with her husband.
Kidman, 51, recently revealed that she would have loved to have had more children with Urban, 51.
'We go, "Oh gosh, I wonder if we met when we were 25, then we could have had 10 of them!"' Kidman told the publication.
'But Keith says, "Stop the wanting mind." It’s far better to be completely in love and satiated with what you’ve been given, what we’ve been given.'
The couple share two daughters, Sunday Rose, 10 and Faith Margaret, eight.
