In 2009, Keith Urban and Nicole Kidman talked to PEOPLE about having more children and said, "We always say, 'If it's God's plan.” As previously reported, that day came true on Dec. 28 when they became the proud parents of Faith Margaret, their daughter born to a gestational carrier at the Women's Hospital at Centennial Medical Center in Nashville.

Baby Faith's middle name, Margaret, comes from Kidman's late grandmother, and her first name comes from her parents' faith in having another child.

Kidman has been very open about her past troubles conceiving their first daughter together, Sunday, and a friend of the couple says, "They never gave up faith they'd have another child together. They feel blessed, they’re just thrilled."

Baby Faith Margaret joins sister Sunday Rose, 2, as well as half sister Isabella Cruise, 18, and half brother Connor Cruise, 15.
