Out of the blue Keith Urban and Nicole Kidman announce the arrival of their new baby girl who was born in December. They did something most celebrities can't seem to keep, a secret.

Sunday Rose has a little sister. Keith Urban and Nicole Kidman have made the surprise announcement that they have a new daughter. She was born via surrogate on December 28th in a Nashville hospital. They've named her Faith Margaret Kidman Urban. Over the weekend, Urban and Kidman hit two awards shows with no mention of a new baby. They were interviewed on the red carpet at the Critics' Choice Movie Awards Friday and the Golden Globes on Sunday. She was nominated at both for her role in "Rabbit Hole." In addition to their two daughters together, Kidman also has two teenage kids, a girl and a boy, she and Tom Cruise adopted when they were married. Story from Associated Press
