Nicole Kidman shares rare photo of daughter Faith with sweet birthday message

Nicole Kidman treated fans to a surprise look at her rarely photographed daughter, Faith Margaret Kidman Urban, who turned 9 on Saturday.

The "Bombshell" actress posted the sweet photos to her Instagram, along with the caption, "Our baby girl is now 9! We love you so much precious precious girl. Happy birthday Faith!"

The first photo is a throwback, featuring Kidman cuddling a messy-haired baby Faith, before switching to the present in the second snapshot -- a chocolate cake with "Happy 9th Birthday Faith" delicately written in pink icing, which is surrounded by 10 equally pink candles.

Kidman's famous friends and co-stars flooded the comments section with well wishes, including Gwyneth Paltrow, who marveled "What a photo" and Reese Witherspoon, who sweetly wrote, "Stunning!! Happy Birthday Faith!"

The actress and her husband, Keith Urban, are parents to Faith and another daughter, 11-year-old Sunday Rose. Both parents, who tied the knot in 2006, tend to keep their daughters away from the limelight and rarely share photos of them to social media.
