Nicole Kidman "can't stop kissing" her new baby daughter.

The 'Rabbit Hole' actress and husband Keith Urban became parents to daughter Faith Margaret through a gestational carrier in December and the 43-year-old beauty is besotted with the infant.

She said: "She's divine, she's growing and an absolute little bundle of yumminess.

"I can't stop kissing her!"

Nicole - who also has two-year-old daughter Sunday Rose with Keith and adopted children, Isabella, 18, and 15-year-old Connor, with ex-husband Tom Cruise - thinks her life has got richer since she became a mother.

She added to 'E! News': "I love every stage, I just love raising children. I love the humour and the honesty. They bring so much to your life!"

Nicole was recently nominated for an Academy Award for her performance in 'Rabbit Hole' and she admits her emotional response when she learned the news left Sunday Rose confused.

She recalled: "It was just a really joyful moment, but I was crying because, you know, sometimes you cry when you're happy. Sunday was like, 'Why are you sad?' and I was like, 'Mommy's not sad, Mommy's happy.' But that's confusing for a two year old."
