People.com reports that Sunday Rose, Kidman and Urban's first child together, was born on Monday morning in Nashville.

Spokesman Paul Freundlich confirmed the news, saying, "Husband Keith was by Nicole's side, and mother and baby are very well."

Kidman, 41, has two adopted children with ex-husband Tom Cruise: Isabella, 15, and Connor, 13.

Kidman first announced her pregnancy in January, following rampant speculation.

The star couple married just over two years ago in Sydney, Australia.
