For many parents, a newborn's birth is immediately accompanied by a newspaper announcement, a lawn sign, and, maybe these days, dozens of social media photo uploads.

Not so for Keith Urban and Nicole Kidman.

The celebrity couple put out an announcement only after the Golden Globes that they became the proud parents of a baby girl on Dec. 28, reports People magazine.

Faith Margaret Kidman Urban was born through a gestational carrier and is the biological daughter of Kidman and Urban, People reports.

"Our family is truly blessed, and just so thankful, to have been given the gift of baby Faith Margaret," the family says in a statement. "No words can adequately convey the incredible gratitude that we feel for everyone who was so supportive throughout this process, in particular our gestational carrier."

A gestational carrier is defined by babycenter.com as someone who carries the biological embryo of another couple to term. Often, the embryo is conceived through in vitro fertilization, although sometimes an egg, sperm or an embryo can be donated for the process.

Babycenter.com states: "Using a gestational carrier is an emotionally intense and legally complex arrangement. It's officially recognized in only a handful of states and is still illegal in others. The process can require vast amounts of time, money, and patience to succeed."
