The lovely Mrs. Keith Urban -- also known as Academy Award winning actress Nicole Kidman -- opened up about the surrogacy and birth of the couple's new daughter, Faith Margaret, in an interview with Australia's '60 Minutes.'

Kidman, who called her situation a "roller coaster ride with fertility," said that seeing Faith born was a "deeply emotional" and "moving" experience. "Having given birth and then being there to see my child born in that way, I felt so much love for our surrogate, gestational carrier," the redheaded actress said.

Kidman has been the subject of much criticism for her repeated usage of that particular term "gestational carrier," rather than the more familiar phrase "surrogate" when discussing the birth. Turns out, it's not just a matter of semantics for the actress. It's a matter of correctness, and the actress was happy to clarify her word choice. "We were trying to be accurate," Kidman explained. "The term 'gestational carrier' is used if it's your biological child and if it isn't, then you use 'surrogate.' I mean, who knows what it is? But she's the most wonderful woman to do this for us."

Kidman was also frank about the couple's desire to expand their family and the struggle to get pregnant. "Anyone that's been in the place of wanting a child knows the disappointment, the pain and the loss you go through," she said. "Struggling with fertility is such a big thing and it's not something that I would run away from talking about." She also got emotional and tearful when admitting, "We were in a place of desperately wanting another child and I couldn't get pregnant. I get emotional just talking about it, because I'm so grateful."

Kidman and Urban are also parents to 2-year-old Sunday Rose. Kidman also adopted two children during her marriage to Tom Cruise: Isabella, 18, and Connor, 15.
