This has been the biggest surprise of my life, to tell you the truth. I thought I was kind of past the point where this could be a reality for me. So, it's been a big surprise and the most wonderful."

Nicole Kidman

Nicole Kidman adopted two children, Isabella and Connor, with her ex-husband, Tom Cruise. At 40, she had her first biological child, Sunday Rose, with husband, Keith Urban.

Anyone that's been in the place of wanting a child knows the disappointment, the pain and the loss you go through. Struggling with fertility is such a big thing and it's not something that I would run away from talking about. 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."
