Nicole Kidman

The 'Eyes Wide Shut' actress has tragically struggled with infertility, having suffered an ectopic pregnancy and a miscarriage during her marriage to Tom Cruise - although the pair did adopt daughter Bella and son Connor together.

After marrying country singer Keith Urban, the ‘Aquaman’ star welcomed daughter Sunday in 2008 when she was 41 years old.

Discussing the pregnancy with Who magazine, Nicole said: "I've done all the stuff you can possibly do to try to get pregnant. So, the way it just happened with Sunday was like, ‘What?' The percentages were so low. It is the miracle in my life."

The couple then welcomed second daughter Faith, via surrogate, three years later.
