"Earlier this morning Nic gave birth to our beautiful baby girl, Sunday Rose Kidman Urban," writes a post on Keith Urban's Web site. "We want to thank everybody that has kept us in their thoughts and prayers. We feel very blessed and grateful that we can share this joy with all of you today."

According to Paul Freundlich, a publicist for the singer, Kidman and Urban’s baby, Sunday weighed 6 pounds, 7 1/2 ounces.

Nicole Kidman and Keith Urban married in June 2006. Nic has two children, Isabella and Connor, with her ex-husband Tom Cruise.

In a concert in Nashville, Urban said, "I'm going to dedicate a song to my very, very, very, very, very pregnant wife."
