Nicole Kidman receives second daughter from surrogate mother

Oscar-winning actress Nicole Kidman and her country star husband, Keith Urban, have added a second daughter to their family, born via a surrogate mother in the United States.

The Australian couple today announced the arrival of Faith Margaret Kidman Urban, born on December 28 at a Nashville, Tennessee, hospital. Faith was born at the Centennial Medical Centre under a veil of secrecy, involving the celebrity couple booking out the entire top floor of the hospital and secretly entering the facility via a staff-only service elevator, ABC Online says.

"Our family is truly blessed, and just so thankful, to have been given the gift of baby Faith Margaret," the family said in a statement.

"No words can adequately convey the incredible gratitude that we feel for everyone who was so supportive throughout this process, in particular our gestational carrier."

Kidman and Urban, both 43, have a two-year-old daughter, Sunday Rose. The trio were in Australia visiting family last month, but they flew back to the US on December 23 to be in Nashville in time for the birth, Herald Sun reports.
