Nicole Kidman is somebody who's spoken candidly about her issues with having children in the past. At one point she feared that it would never happen for her at all. At ectopic pregnancy early in her marriage to Tom Cruise; when Kidman was still in her twenties; was at one point thought to have left her unable to have children. The couple was so sure that it wasn't on the cards for them that they adopted instead.
She was therefore as surprised as anybody when she became pregnant during her second marriage, to Keith Urban, in 2008. She was 41 at the time and stated that having tried 'everything' to get pregnant in the past, this time it just happened naturally with no medical or external help required at all. Three years later, at 44, the couple welcomed their second child. Kidman describes them as a blessing and a miracle.
