Kidman's longtime priest, Rev. Paul Coleman, performed the traditional Catholic ceremony Saturday night at Cardinal Cerretti Chapel, which overlooks the ocean.
Kidman wore an ivory Nicolas Ghesquire gown and was escorted down the aisle by her father, Antony, the Sydney Morning Herald reports.
Her sister, Antonia, was her matron of honor and her 13-year-old daughter Isabella and actress Naomi Watts as bridesmaids.
Isabella and 11-year-old Connor, are the children Kidman adopted with Tom Cruise when they were married. They divorced in 2001.
Urban and Kidman were both born in Australia but will live in Urban's Nashville home.
